+# Brooklyn-Based Board Gaming signup sheet
+
+This directory contains a small web application that acts as a signup
+sheet and attendee tracking system for [my local board gaming
+meetup](https://www.meetup.com/brooklyn-based-board-gaming/).
+
+## Development
+
+### Installing dependencies
+
+#### With Nix + Docker ("blessed way")
+
+Prerequisites:
+
+-   [Nix](https://nixos.org/)
+-   [lorri](https://github.com/nix-community/lorri)
+-   [Docker](https://www.docker.com/)
+
+From this directory in a full checkout of depot, run the following
+commands to install all development dependencies:
+
+``` shell-session
+$ pwd
+/path/to/depot/users/grfn/bbbg
+$ direnv allow
+$ lorri watch --once # Wait for a single nix shell build
+```
+
+Then, to run a docker container with the development database:
+
+``` shell-session
+$ pwd
+/path/to/depot/users/grfn/bbbg
+$ arion up -d
+```
+
+#### Choose-your-own-adventure
+
+Note that the **authoritative** source for dev dependencies is the `shell.nix`
+file in this directory - those may diverge from what's written here; if so
+follow those versions rather than these.
+
+-   Install the [clojure command-line
+    tools](https://clojure.org/guides/getting_started), with openjdk 11
+-   Install and run a postgresql 12 database, with:
+    -   A user with superuser priveleges, the username `bbbg` and the
+        password `password`
+    -   A database called `bbbg` owned by that user.
+-   Export the following environment variables in a context visible by
+    whatever method you use to run the application:
+    -   `PGHOST=localhost`
+    -   `PGUSER=bbbg`
+    -   `PGDATABASE=bbbg`
+    -   `PGPASSWORD=bbbg`
+
+### Running the application
+
+Before running the app, you'll need an oauth2 client-id and client secret for a
+Discord app. The application can either load those from a
+[pass](https://www.passwordstore.org/) password store, or read them from
+plaintext files in a directory. In either case, they should be accessible at the
+paths `bbbg/discord-client-id` and `bbbg/discord-client-secret` respectively.
+
+#### From the command line
+
+``` shell-session
+$ clj -A:dev
+Clojure 1.11.0-alpha3
+user=> (require 'bbbg.core)
+nil
+user=> ;; Optionally, if you're using a directory with plaintext files for the discord client ID and client secret:
+user=> (bbbg.util.dev-secrets/set-backend! [:dir "/path/to/that/directory"])
+user=> (bbbg.core/run-dev)
+##<SystemMap>
+user=> (bbbg.db/migrate! (:db bbbg.core/system))
+11:57:26.536 [main] INFO  migratus.core - Starting migrations {  }
+11:57:26.538 [main] INFO  com.zaxxer.hikari.HikariDataSource - HikariPool-1 - Starting... {  }
+11:57:26.883 [main] INFO  com.zaxxer.hikari.pool.HikariPool - HikariPool-1 - Added connection com.impossibl.postgres.jdbc.PGDirectConnection@3cae770e {  }
+11:57:26.884 [main] INFO  com.zaxxer.hikari.HikariDataSource - HikariPool-1 - Start completed. {  }
+11:57:26.923 [main] INFO  migratus.core - Ending migrations {  }
+nil
+```
+
+This will run a web server for the application listening at
+<http://localhost:8888>
+
+#### In Emacs, with [CIDER](https://docs.cider.mx/cider/index.html) + [direnv](https://github.com/wbolster/emacs-direnv)
+
+Open `//users/grfn/bbbg/src/bbbg/core.clj` in a buffer, then follow the
+instructions at the end of the file
+
+## Deployment
+
+### With nix+terraform
+
+Deployment configuration is located in the `tf.nix` file, which is
+currently tightly coupled to my own infrastructure and AWS account but
+could hypothetically be adjusted to be general-purpose.
+
+To deploy a new version of the application, after following "installing
+dependencies" above, run the following command in a context with ec2
+credentials available:
+
+``` shell-session
+$ terraform apply
+```
+
+The current deploy configuration includes:
+
+-   An ec2 instance running nixos, with a postgresql database and the
+    bbbg application running as a service, behind nginx with an
+    auto-renewing letsencrypt cert
+-   The DNS A record for `bbbg.gws.fyi` pointing at that ec2 instance,
+    in the cloudflare zone for `gws.fyi`
+
+### Otherwise
+
+¯\\\_(ツ)_/¯
+
+You'll need:
+
+-   An uberjar for bbbg; the canonical way of building that is `nix-build
+    /path/to/depot -A users.grfn.bbbg.server-jar` but I\'m not sure how that
+    works outside of nix
+-   A postgresql database
+-   Environment variables telling the app how to connect to that
+    database. See `config.systemd.services.bbbg-server.environment` in
+    `module.nix` for which env vars are currently being exported by the
+    NixOS module that runs the production version of the app

+#+TITLE: Tomato Sauce
+#+OPTIONS: toc:nil num:nil
+#+HTML_HEAD: <link rel="stylesheet" href="../main.css">
+
+This is a general, all-purpose framework for turning some form of tomatoes into
+some form of sauce. You can use fresh tomatoes or canned (the latter are really
+quite surprisingly good sometimes), and include or omit garlic, basil, or other
+add-ins. The only real non-negotiable ingredients are tomatoes (duh), onion, and
+some kind of fat (I prefer butter).
+
+* Sauce
+
+1. *Prep*. If starting with canned tomatoes, skip this step. if starting with
+   whole tomatoes (which you should really only ever do if you grew them
+   yourself or got them fresh at a farmers market, grocery store tomatoes are
+   kinda sad), first, peel the tomatoes. The easiest way to do this is to score
+   them with an X pattern cut as shallow as possible while still breaking the
+   skin, trying to cover the whole surface area of the tomato, blanch them
+   briefly in boiling water, then dunk into an ice bath. After this, the skins
+   will slip right off.  After peeling, cut out the stem, core, and any green or
+   brown bits, and go to the next step
+
+2. *Base layer*. Couple of variables here, though a perfectly good (in fact, my
+   usual go-to) tomato sauce can also skip this entire step:
+   - If you want meat with your sauce (pancetta/guanciale/bacon for an
+     amatriciana, ground beef or pork for a bolognese) you'll start out by
+     sautéing that in some sort of fat (probably olive oil), less fat for meat
+     with a lot of fat already in it, to brown and render out fat from the meat
+   - If you want onion in the final sauce, you'll chop them finely and sauté
+     them with whatever fat you've got (either from the meat, or olive oil or
+     butter if you're not making a meat sauce). Remember to always add a *bit*
+     of salt when sautéing onion like this, not for flavor but to draw out the
+     moisture. If you just want onion flavor but not bits of onion in the final
+     sauce, it's added whole later (so ignore this bullet point).
+   - If you feel like it (sometimes I do, usually I don't) you can also mince
+     garlic here and sauté that in with everything else. Add a little after the
+     onion, as garlic cooks slower than onion unless you want something roastier
+     (usually you don't for tomato sauce)
+   - The traditional (so I'm told) thing to do with amatriciana, but also nice
+     with all variations, is to add in a little crushed red pepper with the
+     fat to flavor it slightly, but do this late so it doesn't burn
+   - If you have tomato paste on hand and feel like using it, it's also nice to
+     fry that in the oil for a little bit - usually I'd do that around the same
+     time as the garlic
+
+   If you're making tomato *paste* from your sauce, skip all of this - paste is
+   an ingredient, not a sauce on its own, so imo should be as neutral as
+   possible (i.e. just tomato).
+
+3. *Tomato layer*. Not a whole lot to do here, just add all of your tomatoes -
+   either your peeled and de-cored tomatoes from step 1 if you're using whole
+   tomatoes, or an entire can of whole, peeled san marzano tomatoes, including
+   the juice in the can - to a pot over medium-high heat. If you need more fat
+   or if you skipped step 2, this is where you'd add it - a classic and my
+   personal favorite is like 2/3rds to 3/4ths of a stick of butter, but you can
+   also go with olive oil. If you skipped the onion in step 2, add that here
+   too - usually that'd just be a fist-sized amount of onion or so peeled but
+   left with the stem on so you can fish it out from your final sauce later (and
+   snack on it!). Also salt here, again not to taste but primarily to draw out
+   moisture from the various ingredients.
+
+4. You can cook that for a wide variety of times, especially depending on how
+   hot you make your stove - there ends up being *lot* of liquid in there, so
+   you can go (in my experience) a reasonable amount hotter than you expect
+   without burning the sauce, though obviously your mileage may vary. The main
+   thing you're looking for is the whole chunks of tomato to break down, and the
+   whole sauce to get a texture that looks like it'll end up sticking to pasta
+   nicely. In all versions of this, stir pretty regularly with a wooden spoon,
+   and use the spoon to crush the big chunks of tomato occasionally.
+
+5. *Final layer*. Usually I don't do anything here - but if you feel
+   like it, usually right as you take stuff off the heat is where you'd add
+   basil, if you're using it. You can also add sugar to balance out too much
+   acidity from an especially acidic tomato here - I'm not going to tell anyone.
+   Also salt, but make sure to account for the extra salt you're gonna get from
+   the pasta water (see step 6)
+
+6. *Pasta*. You know how to cook pasta, I'm not going to tell you that. But,
+   like, salt your water until it tastes too salty, and remember to move the
+   pasta itself *directly* into the sauce pot from the pasta pot before it's
+   completely done cooking and without straining, bringing along some of the
+   pasta water (and a little extra for good measure) then finishing the pasta in
+   the sauce. You know, the thing you do for pasta. Remember the pasta water
+   will have salt in it, so adjust for that when salting the sauce overall (I
+   have made this mistake and ended up with too-salty pasta sauce).
+
+* Paste
+
+Start with the above recipe for tomato sauce, noting especially that (in my
+opinion) you should skip step 2 entirely. Keep cooking the sauce until it's
+*too* thick for pasta sauce (but don't burn it!), then spread it out across some
+sort of lined sheet pan (like a silpat, if you've got one) and bake in the oven
+at like 250-300 degrees for a *hell* of a long time - I've seen this take like
+10 hours, for an especially juicy batch of tomatoes, but obviously keep a close
+eye on it because it *definitely will burn* eventually. You're looking for the
+end result to be the texture of tomato paste, because that's what the recipe is
+for.  Especially if you're using garden-grown or otherwise fresh tomatoes,
+you'll notice quite a few seeds in the final product - don't worry too much
+about those, they've never bothered me. Once everything's done and cooled down,
+store in a jar in a fridge, topped with olive oil to seal things off and prevent
+oxidation. Use in all your future endeavors, including the tomato sauce recipe
+above itself. Tomato sauce is a beautiful oroborous.

+#+TITLE:Org-Clubhouse
+
+Simple, unopinionated integration between Emacs's [[https://orgmode.org/][org-mode]] and the [[https://clubhouse.io/][Clubhouse]]
+issue tracker
+
+(This used to be at urbint/org-clubhouse, by the way, but moved here as it's
+more of a personal project than a company one)
+
+* Installation
+
+** [[https://github.com/quelpa/quelpa][Quelpa]]
+
+#+BEGIN_SRC emacs-lisp
+(quelpa '(org-clubhouse
+          :fetcher github
+          :repo "glittershark/org-clubhouse"))
+#+END_SRC
+
+** [[https://github.com/hlissner/doom-emacs/][DOOM Emacs]]
+
+#+BEGIN_SRC emacs-lisp
+;; in packages.el
+(package! org-clubhouse
+  :recipe (:fetcher github
+           :repo "glittershark/org-clubhouse"
+           :files ("*")))
+
+;; in config.el
+(def-package! org-clubhouse)
+#+END_SRC
+
+** [[http://spacemacs.org/][Spacemacs]]
+#+BEGIN_SRC emacs-lisp
+;; in .spacemacs (SPC+fed)
+   dotspacemacs-additional-packages
+    '((org-clubhouse :location (recipe :fetcher github :repo "glittershark/org-clubhouse")))
+#+END_SRC
+
+
+* Setup
+
+Once installed, you'll need to set three global config vars:
+
+#+BEGIN_SRC emacs-lisp
+(setq org-clubhouse-auth-token "<your-token>"
+      org-clubhouse-team-name "<your-team-name>"
+      org-clubhouse-username "<your-username>")
+#+END_SRC
+
+You can generate a new personal API token by going to the "API Tokens" tab on
+the "Settings" page in the clubhouse UI.
+
+Note that ~org-clubhouse-username~ needs to be set to your *mention name*, not
+your username, as currently there's no way to get the ID of a user given their
+username in the clubhouse API
+
+* Usage
+
+** Reading from clubhouse
+
+- ~org-clubhouse-headlines-from-query~
+  Create org-mode headlines from a [[https://help.clubhouse.io/hc/en-us/articles/360000046646-Searching-in-Clubhouse-Story-Search][clubhouse query]] at the cursor's current
+  position, prompting for the headline indentation level and clubhouse query
+  text
+- ~org-clubhouse-headline-from-story~
+  Prompts for headline indentation level and the title of a story (which will
+  complete using the titles of all stories in your Clubhouse workspace) and
+  creates an org-mode headline from that story
+- ~org-clubhouse-headline-from-story-id~
+  Creates an org-mode headline directly from the ID of a clubhouse story
+
+** Writing to clubhouse
+
+- ~org-clubhouse-create-story~
+  Creates a new Clubhouse story from the current headline, or if a region of
+  headlines is selected bulk-creates stories with all those headlines
+- ~org-clubhouse-create-epic~
+  Creates a new Clubhouse epic from the current headline, or if a region of
+  headlines is selected bulk-creates epics with all those headlines
+- ~org-clubhouse-create-story-with-task-list~
+  Creates a Clubhouse story from the current headline, making all direct
+  children of the headline into tasks in the task list of the story
+- ~org-clubhouse-push-task-list~
+  Writes each child element of the current clubhouse element as a task list
+  item of the associated clubhouse ID.
+- ~org-clubhouse-update-story-title~
+  Updates the title of the Clubhouse story linked to the current headline with
+  the text of the headline
+- ~org-clubhouse-update-description~
+  Update the status of the Clubhouse story linked to the current element with
+  the contents of a drawer inside the element called DESCRIPTION, if any exists
+- ~org-clubhouse-claim~
+  Adds the user configured in ~org-clubhouse-username~ as the owner of the
+  clubhouse story associated with the headline at point
+
+*** Automatically updating Clubhouse story statuses
+
+Org-clubhouse can be configured to update the status of stories as you update
+their todo-keyword in org-mode. To opt-into this behavior, set the
+~org-clubhouse-mode~ minor-mode:
+
+#+BEGIN_SRC emacs-lisp
+(add-hook 'org-mode-hook #'org-clubhouse-mode nil nil)
+#+END_SRC
+
+The mapping from org-mode todo-keywords is configured via the
+~org-clubhouse-state-alist~ variable, which should be an [[https://www.gnu.org/software/emacs/manual/html_node/elisp/Association-Lists.html][alist]] mapping (string)
+[[https://orgmode.org/manual/Workflow-states.html][org-mode todo-keywords]] to the (string) names of their corresponding workflow
+state. You can have todo-keywords that don't map to a workflow state (I use this
+in my workflow extensively) and org-clubhouse will just preserve the previous
+state of the story when moving to that state.
+
+An example config:
+
+#+BEGIN_SRC emacs-lisp
+(setq org-clubhouse-state-alist
+      '(("TODO"   . "To Do")
+        ("ACTIVE" . "In Progress")
+        ("DONE"   . "Done")))
+#+END_SRC
+
+* Philosophy
+
+I use org-mode every single day to manage tasks, notes, literate programming,
+etc. Part of what that means for me is that I already have a system for the
+structure of my .org files, and I don't want to sacrifice that system for any
+external tool. Updating statuses, ~org-clubhouse-create-story~, and
+~org-clubhouse-headline-from-story~ are my bread and butter for that reason -
+rather than having some sort of bidirectional sync that pulls down full lists of
+all the stories in Clubhouse (or whatever issue tracker / project management
+tool I'm using at the time). I can be in a mode where I'm taking meeting notes,
+think of something that I need to do, make it a TODO headline, and make that
+TODO headline a clubhouse story. That's the same reason for the DESCRIPTION
+drawers rather than just sending the entire contents of a headline to
+Clubhouse - I almost always want to write things like personal notes, literate
+code, etc inside of the tasks I'm working on, and don't always want to share
+that with Clubhouse.

+              GNU GENERAL PUBLIC LICENSE
+                Version 3, 29 June 2007
+
+ Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+                     Preamble
+
+  The GNU General Public License is a free, copyleft license for
+software and other kinds of works.
+
+  The licenses for most software and other practical works are designed
+to take away your freedom to share and change the works.  By contrast,
+the GNU General Public License is intended to guarantee your freedom to
+share and change all versions of a program--to make sure it remains free
+software for all its users.  We, the Free Software Foundation, use the
+GNU General Public License for most of our software; it applies also to
+any other work released this way by its authors.  You can apply it to
+your programs, too.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+them if you wish), that you receive source code or can get it if you
+want it, that you can change the software or use pieces of it in new
+free programs, and that you know you can do these things.
+
+  To protect your rights, we need to prevent others from denying you
+these rights or asking you to surrender the rights.  Therefore, you have
+certain responsibilities if you distribute copies of the software, or if
+you modify it: responsibilities to respect the freedom of others.
+
+  For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must pass on to the recipients the same
+freedoms that you received.  You must make sure that they, too, receive
+or can get the source code.  And you must show them these terms so they
+know their rights.
+
+  Developers that use the GNU GPL protect your rights with two steps:
+(1) assert copyright on the software, and (2) offer you this License
+giving you legal permission to copy, distribute and/or modify it.
+
+  For the developers' and authors' protection, the GPL clearly explains
+that there is no warranty for this free software.  For both users' and
+authors' sake, the GPL requires that modified versions be marked as
+changed, so that their problems will not be attributed erroneously to
+authors of previous versions.
+
+  Some devices are designed to deny users access to install or run
+modified versions of the software inside them, although the manufacturer
+can do so.  This is fundamentally incompatible with the aim of
+protecting users' freedom to change the software.  The systematic
+pattern of such abuse occurs in the area of products for individuals to
+use, which is precisely where it is most unacceptable.  Therefore, we
+have designed this version of the GPL to prohibit the practice for those
+products.  If such problems arise substantially in other domains, we
+stand ready to extend this provision to those domains in future versions
+of the GPL, as needed to protect the freedom of users.
+
+  Finally, every program is threatened constantly by software patents.
+States should not allow patents to restrict development and use of
+software on general-purpose computers, but in those that do, we wish to
+avoid the special danger that patents applied to a free program could
+make it effectively proprietary.  To prevent this, the GPL assures that
+patents cannot be used to render the program non-free.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+                TERMS AND CONDITIONS
+
+  0. Definitions.
+
+  "This License" refers to version 3 of the GNU General Public License.
+
+  "Copyright" also means copyright-like laws that apply to other kinds of
+works, such as semiconductor masks.
+
+  "The Program" refers to any copyrightable work licensed under this
+License.  Each licensee is addressed as "you".  "Licensees" and
+"recipients" may be individuals or organizations.
+
+  To "modify" a work means to copy from or adapt all or part of the work
+in a fashion requiring copyright permission, other than the making of an
+exact copy.  The resulting work is called a "modified version" of the
+earlier work or a work "based on" the earlier work.
+
+  A "covered work" means either the unmodified Program or a work based
+on the Program.
+
+  To "propagate" a work means to do anything with it that, without
+permission, would make you directly or secondarily liable for
+infringement under applicable copyright law, except executing it on a
+computer or modifying a private copy.  Propagation includes copying,
+distribution (with or without modification), making available to the
+public, and in some countries other activities as well.
+
+  To "convey" a work means any kind of propagation that enables other
+parties to make or receive copies.  Mere interaction with a user through
+a computer network, with no transfer of a copy, is not conveying.
+
+  An interactive user interface displays "Appropriate Legal Notices"
+to the extent that it includes a convenient and prominently visible
+feature that (1) displays an appropriate copyright notice, and (2)
+tells the user that there is no warranty for the work (except to the
+extent that warranties are provided), that licensees may convey the
+work under this License, and how to view a copy of this License.  If
+the interface presents a list of user commands or options, such as a
+menu, a prominent item in the list meets this criterion.
+
+  1. Source Code.
+
+  The "source code" for a work means the preferred form of the work
+for making modifications to it.  "Object code" means any non-source
+form of a work.
+
+  A "Standard Interface" means an interface that either is an official
+standard defined by a recognized standards body, or, in the case of
+interfaces specified for a particular programming language, one that
+is widely used among developers working in that language.
+
+  The "System Libraries" of an executable work include anything, other
+than the work as a whole, that (a) is included in the normal form of
+packaging a Major Component, but which is not part of that Major
+Component, and (b) serves only to enable use of the work with that
+Major Component, or to implement a Standard Interface for which an
+implementation is available to the public in source code form.  A
+"Major Component", in this context, means a major essential component
+(kernel, window system, and so on) of the specific operating system
+(if any) on which the executable work runs, or a compiler used to
+produce the work, or an object code interpreter used to run it.
+
+  The "Corresponding Source" for a work in object code form means all
+the source code needed to generate, install, and (for an executable
+work) run the object code and to modify the work, including scripts to
+control those activities.  However, it does not include the work's
+System Libraries, or general-purpose tools or generally available free
+programs which are used unmodified in performing those activities but
+which are not part of the work.  For example, Corresponding Source
+includes interface definition files associated with source files for
+the work, and the source code for shared libraries and dynamically
+linked subprograms that the work is specifically designed to require,
+such as by intimate data communication or control flow between those
+subprograms and other parts of the work.
+
+  The Corresponding Source need not include anything that users
+can regenerate automatically from other parts of the Corresponding
+Source.
+
+  The Corresponding Source for a work in source code form is that
+same work.
+
+  2. Basic Permissions.
+
+  All rights granted under this License are granted for the term of
+copyright on the Program, and are irrevocable provided the stated
+conditions are met.  This License explicitly affirms your unlimited
+permission to run the unmodified Program.  The output from running a
+covered work is covered by this License only if the output, given its
+content, constitutes a covered work.  This License acknowledges your
+rights of fair use or other equivalent, as provided by copyright law.
+
+  You may make, run and propagate covered works that you do not
+convey, without conditions so long as your license otherwise remains
+in force.  You may convey covered works to others for the sole purpose
+of having them make modifications exclusively for you, or provide you
+with facilities for running those works, provided that you comply with
+the terms of this License in conveying all material for which you do
+not control copyright.  Those thus making or running the covered works
+for you must do so exclusively on your behalf, under your direction
+and control, on terms that prohibit them from making any copies of
+your copyrighted material outside their relationship with you.
+
+  Conveying under any other circumstances is permitted solely under
+the conditions stated below.  Sublicensing is not allowed; section 10
+makes it unnecessary.
+
+  3. Protecting Users' Legal Rights From Anti-Circumvention Law.
+
+  No covered work shall be deemed part of an effective technological
+measure under any applicable law fulfilling obligations under article
+11 of the WIPO copyright treaty adopted on 20 December 1996, or
+similar laws prohibiting or restricting circumvention of such
+measures.
+
+  When you convey a covered work, you waive any legal power to forbid
+circumvention of technological measures to the extent such circumvention
+is effected by exercising rights under this License with respect to
+the covered work, and you disclaim any intention to limit operation or
+modification of the work as a means of enforcing, against the work's
+users, your or third parties' legal rights to forbid circumvention of
+technological measures.
+
+  4. Conveying Verbatim Copies.
+
+  You may convey verbatim copies of the Program's source code as you
+receive it, in any medium, provided that you conspicuously and
+appropriately publish on each copy an appropriate copyright notice;
+keep intact all notices stating that this License and any
+non-permissive terms added in accord with section 7 apply to the code;
+keep intact all notices of the absence of any warranty; and give all
+recipients a copy of this License along with the Program.
+
+  You may charge any price or no price for each copy that you convey,
+and you may offer support or warranty protection for a fee.
+
+  5. Conveying Modified Source Versions.
+
+  You may convey a work based on the Program, or the modifications to
+produce it from the Program, in the form of source code under the
+terms of section 4, provided that you also meet all of these conditions:
+
+    a) The work must carry prominent notices stating that you modified
+    it, and giving a relevant date.
+
+    b) The work must carry prominent notices stating that it is
+    released under this License and any conditions added under section
+    7.  This requirement modifies the requirement in section 4 to
+    "keep intact all notices".
+
+    c) You must license the entire work, as a whole, under this
+    License to anyone who comes into possession of a copy.  This
+    License will therefore apply, along with any applicable section 7
+    additional terms, to the whole of the work, and all its parts,
+    regardless of how they are packaged.  This License gives no
+    permission to license the work in any other way, but it does not
+    invalidate such permission if you have separately received it.
+
+    d) If the work has interactive user interfaces, each must display
+    Appropriate Legal Notices; however, if the Program has interactive
+    interfaces that do not display Appropriate Legal Notices, your
+    work need not make them do so.
+
+  A compilation of a covered work with other separate and independent
+works, which are not by their nature extensions of the covered work,
+and which are not combined with it such as to form a larger program,
+in or on a volume of a storage or distribution medium, is called an
+"aggregate" if the compilation and its resulting copyright are not
+used to limit the access or legal rights of the compilation's users
+beyond what the individual works permit.  Inclusion of a covered work
+in an aggregate does not cause this License to apply to the other
+parts of the aggregate.
+
+  6. Conveying Non-Source Forms.
+
+  You may convey a covered work in object code form under the terms
+of sections 4 and 5, provided that you also convey the
+machine-readable Corresponding Source under the terms of this License,
+in one of these ways:
+
+    a) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by the
+    Corresponding Source fixed on a durable physical medium
+    customarily used for software interchange.
+
+    b) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by a
+    written offer, valid for at least three years and valid for as
+    long as you offer spare parts or customer support for that product
+    model, to give anyone who possesses the object code either (1) a
+    copy of the Corresponding Source for all the software in the
+    product that is covered by this License, on a durable physical
+    medium customarily used for software interchange, for a price no
+    more than your reasonable cost of physically performing this
+    conveying of source, or (2) access to copy the
+    Corresponding Source from a network server at no charge.
+
+    c) Convey individual copies of the object code with a copy of the
+    written offer to provide the Corresponding Source.  This
+    alternative is allowed only occasionally and noncommercially, and
+    only if you received the object code with such an offer, in accord
+    with subsection 6b.
+
+    d) Convey the object code by offering access from a designated
+    place (gratis or for a charge), and offer equivalent access to the
+    Corresponding Source in the same way through the same place at no
+    further charge.  You need not require recipients to copy the
+    Corresponding Source along with the object code.  If the place to
+    copy the object code is a network server, the Corresponding Source
+    may be on a different server (operated by you or a third party)
+    that supports equivalent copying facilities, provided you maintain
+    clear directions next to the object code saying where to find the
+    Corresponding Source.  Regardless of what server hosts the
+    Corresponding Source, you remain obligated to ensure that it is
+    available for as long as needed to satisfy these requirements.
+
+    e) Convey the object code using peer-to-peer transmission, provided
+    you inform other peers where the object code and Corresponding
+    Source of the work are being offered to the general public at no
+    charge under subsection 6d.
+
+  A separable portion of the object code, whose source code is excluded
+from the Corresponding Source as a System Library, need not be
+included in conveying the object code work.
+
+  A "User Product" is either (1) a "consumer product", which means any
+tangible personal property which is normally used for personal, family,
+or household purposes, or (2) anything designed or sold for incorporation
+into a dwelling.  In determining whether a product is a consumer product,
+doubtful cases shall be resolved in favor of coverage.  For a particular
+product received by a particular user, "normally used" refers to a
+typical or common use of that class of product, regardless of the status
+of the particular user or of the way in which the particular user
+actually uses, or expects or is expected to use, the product.  A product
+is a consumer product regardless of whether the product has substantial
+commercial, industrial or non-consumer uses, unless such uses represent
+the only significant mode of use of the product.
+
+  "Installation Information" for a User Product means any methods,
+procedures, authorization keys, or other information required to install
+and execute modified versions of a covered work in that User Product from
+a modified version of its Corresponding Source.  The information must
+suffice to ensure that the continued functioning of the modified object
+code is in no case prevented or interfered with solely because
+modification has been made.
+
+  If you convey an object code work under this section in, or with, or
+specifically for use in, a User Product, and the conveying occurs as
+part of a transaction in which the right of possession and use of the
+User Product is transferred to the recipient in perpetuity or for a
+fixed term (regardless of how the transaction is characterized), the
+Corresponding Source conveyed under this section must be accompanied
+by the Installation Information.  But this requirement does not apply
+if neither you nor any third party retains the ability to install
+modified object code on the User Product (for example, the work has
+been installed in ROM).
+
+  The requirement to provide Installation Information does not include a
+requirement to continue to provide support service, warranty, or updates
+for a work that has been modified or installed by the recipient, or for
+the User Product in which it has been modified or installed.  Access to a
+network may be denied when the modification itself materially and
+adversely affects the operation of the network or violates the rules and
+protocols for communication across the network.
+
+  Corresponding Source conveyed, and Installation Information provided,
+in accord with this section must be in a format that is publicly
+documented (and with an implementation available to the public in
+source code form), and must require no special password or key for
+unpacking, reading or copying.
+
+  7. Additional Terms.
+
+  "Additional permissions" are terms that supplement the terms of this
+License by making exceptions from one or more of its conditions.
+Additional permissions that are applicable to the entire Program shall
+be treated as though they were included in this License, to the extent
+that they are valid under applicable law.  If additional permissions
+apply only to part of the Program, that part may be used separately
+under those permissions, but the entire Program remains governed by
+this License without regard to the additional permissions.
+
+  When you convey a copy of a covered work, you may at your option
+remove any additional permissions from that copy, or from any part of
+it.  (Additional permissions may be written to require their own
+removal in certain cases when you modify the work.)  You may place
+additional permissions on material, added by you to a covered work,
+for which you have or can give appropriate copyright permission.
+
+  Notwithstanding any other provision of this License, for material you
+add to a covered work, you may (if authorized by the copyright holders of
+that material) supplement the terms of this License with terms:
+
+    a) Disclaiming warranty or limiting liability differently from the
+    terms of sections 15 and 16 of this License; or
+
+    b) Requiring preservation of specified reasonable legal notices or
+    author attributions in that material or in the Appropriate Legal
+    Notices displayed by works containing it; or
+
+    c) Prohibiting misrepresentation of the origin of that material, or
+    requiring that modified versions of such material be marked in
+    reasonable ways as different from the original version; or
+
+    d) Limiting the use for publicity purposes of names of licensors or
+    authors of the material; or
+
+    e) Declining to grant rights under trademark law for use of some
+    trade names, trademarks, or service marks; or
+
+    f) Requiring indemnification of licensors and authors of that
+    material by anyone who conveys the material (or modified versions of
+    it) with contractual assumptions of liability to the recipient, for
+    any liability that these contractual assumptions directly impose on
+    those licensors and authors.
+
+  All other non-permissive additional terms are considered "further
+restrictions" within the meaning of section 10.  If the Program as you
+received it, or any part of it, contains a notice stating that it is
+governed by this License along with a term that is a further
+restriction, you may remove that term.  If a license document contains
+a further restriction but permits relicensing or conveying under this
+License, you may add to a covered work material governed by the terms
+of that license document, provided that the further restriction does
+not survive such relicensing or conveying.
+
+  If you add terms to a covered work in accord with this section, you
+must place, in the relevant source files, a statement of the
+additional terms that apply to those files, or a notice indicating
+where to find the applicable terms.
+
+  Additional terms, permissive or non-permissive, may be stated in the
+form of a separately written license, or stated as exceptions;
+the above requirements apply either way.
+
+  8. Termination.
+
+  You may not propagate or modify a covered work except as expressly
+provided under this License.  Any attempt otherwise to propagate or
+modify it is void, and will automatically terminate your rights under
+this License (including any patent licenses granted under the third
+paragraph of section 11).
+
+  However, if you cease all violation of this License, then your
+license from a particular copyright holder is reinstated (a)
+provisionally, unless and until the copyright holder explicitly and
+finally terminates your license, and (b) permanently, if the copyright
+holder fails to notify you of the violation by some reasonable means
+prior to 60 days after the cessation.
+
+  Moreover, your license from a particular copyright holder is
+reinstated permanently if the copyright holder notifies you of the
+violation by some reasonable means, this is the first time you have
+received notice of violation of this License (for any work) from that
+copyright holder, and you cure the violation prior to 30 days after
+your receipt of the notice.
+
+  Termination of your rights under this section does not terminate the
+licenses of parties who have received copies or rights from you under
+this License.  If your rights have been terminated and not permanently
+reinstated, you do not qualify to receive new licenses for the same
+material under section 10.
+
+  9. Acceptance Not Required for Having Copies.
+
+  You are not required to accept this License in order to receive or
+run a copy of the Program.  Ancillary propagation of a covered work
+occurring solely as a consequence of using peer-to-peer transmission
+to receive a copy likewise does not require acceptance.  However,
+nothing other than this License grants you permission to propagate or
+modify any covered work.  These actions infringe copyright if you do
+not accept this License.  Therefore, by modifying or propagating a
+covered work, you indicate your acceptance of this License to do so.
+
+  10. Automatic Licensing of Downstream Recipients.
+
+  Each time you convey a covered work, the recipient automatically
+receives a license from the original licensors, to run, modify and
+propagate that work, subject to this License.  You are not responsible
+for enforcing compliance by third parties with this License.
+
+  An "entity transaction" is a transaction transferring control of an
+organization, or substantially all assets of one, or subdividing an
+organization, or merging organizations.  If propagation of a covered
+work results from an entity transaction, each party to that
+transaction who receives a copy of the work also receives whatever
+licenses to the work the party's predecessor in interest had or could
+give under the previous paragraph, plus a right to possession of the
+Corresponding Source of the work from the predecessor in interest, if
+the predecessor has it or can get it with reasonable efforts.
+
+  You may not impose any further restrictions on the exercise of the
+rights granted or affirmed under this License.  For example, you may
+not impose a license fee, royalty, or other charge for exercise of
+rights granted under this License, and you may not initiate litigation
+(including a cross-claim or counterclaim in a lawsuit) alleging that
+any patent claim is infringed by making, using, selling, offering for
+sale, or importing the Program or any portion of it.
+
+  11. Patents.
+
+  A "contributor" is a copyright holder who authorizes use under this
+License of the Program or a work on which the Program is based.  The
+work thus licensed is called the contributor's "contributor version".
+
+  A contributor's "essential patent claims" are all patent claims
+owned or controlled by the contributor, whether already acquired or
+hereafter acquired, that would be infringed by some manner, permitted
+by this License, of making, using, or selling its contributor version,
+but do not include claims that would be infringed only as a
+consequence of further modification of the contributor version.  For
+purposes of this definition, "control" includes the right to grant
+patent sublicenses in a manner consistent with the requirements of
+this License.
+
+  Each contributor grants you a non-exclusive, worldwide, royalty-free
+patent license under the contributor's essential patent claims, to
+make, use, sell, offer for sale, import and otherwise run, modify and
+propagate the contents of its contributor version.
+
+  In the following three paragraphs, a "patent license" is any express
+agreement or commitment, however denominated, not to enforce a patent
+(such as an express permission to practice a patent or covenant not to
+sue for patent infringement).  To "grant" such a patent license to a
+party means to make such an agreement or commitment not to enforce a
+patent against the party.
+
+  If you convey a covered work, knowingly relying on a patent license,
+and the Corresponding Source of the work is not available for anyone
+to copy, free of charge and under the terms of this License, through a
+publicly available network server or other readily accessible means,
+then you must either (1) cause the Corresponding Source to be so
+available, or (2) arrange to deprive yourself of the benefit of the
+patent license for this particular work, or (3) arrange, in a manner
+consistent with the requirements of this License, to extend the patent
+license to downstream recipients.  "Knowingly relying" means you have
+actual knowledge that, but for the patent license, your conveying the
+covered work in a country, or your recipient's use of the covered work
+in a country, would infringe one or more identifiable patents in that
+country that you have reason to believe are valid.
+
+  If, pursuant to or in connection with a single transaction or
+arrangement, you convey, or propagate by procuring conveyance of, a
+covered work, and grant a patent license to some of the parties
+receiving the covered work authorizing them to use, propagate, modify
+or convey a specific copy of the covered work, then the patent license
+you grant is automatically extended to all recipients of the covered
+work and works based on it.
+
+  A patent license is "discriminatory" if it does not include within
+the scope of its coverage, prohibits the exercise of, or is
+conditioned on the non-exercise of one or more of the rights that are
+specifically granted under this License.  You may not convey a covered
+work if you are a party to an arrangement with a third party that is
+in the business of distributing software, under which you make payment
+to the third party based on the extent of your activity of conveying
+the work, and under which the third party grants, to any of the
+parties who would receive the covered work from you, a discriminatory
+patent license (a) in connection with copies of the covered work
+conveyed by you (or copies made from those copies), or (b) primarily
+for and in connection with specific products or compilations that
+contain the covered work, unless you entered into that arrangement,
+or that patent license was granted, prior to 28 March 2007.
+
+  Nothing in this License shall be construed as excluding or limiting
+any implied license or other defenses to infringement that may
+otherwise be available to you under applicable patent law.
+
+  12. No Surrender of Others' Freedom.
+
+  If conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot convey a
+covered work so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you may
+not convey it at all.  For example, if you agree to terms that obligate you
+to collect a royalty for further conveying from those to whom you convey
+the Program, the only way you could satisfy both those terms and this
+License would be to refrain entirely from conveying the Program.
+
+  13. Use with the GNU Affero General Public License.
+
+  Notwithstanding any other provision of this License, you have
+permission to link or combine any covered work with a work licensed
+under version 3 of the GNU Affero General Public License into a single
+combined work, and to convey the resulting work.  The terms of this
+License will continue to apply to the part which is the covered work,
+but the special requirements of the GNU Affero General Public License,
+section 13, concerning interaction through a network will apply to the
+combination as such.
+
+  14. Revised Versions of this License.
+
+  The Free Software Foundation may publish revised and/or new versions of
+the GNU General Public License from time to time.  Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+  Each version is given a distinguishing version number.  If the
+Program specifies that a certain numbered version of the GNU General
+Public License "or any later version" applies to it, you have the
+option of following the terms and conditions either of that numbered
+version or of any later version published by the Free Software
+Foundation.  If the Program does not specify a version number of the
+GNU General Public License, you may choose any version ever published
+by the Free Software Foundation.
+
+  If the Program specifies that a proxy can decide which future
+versions of the GNU General Public License can be used, that proxy's
+public statement of acceptance of a version permanently authorizes you
+to choose that version for the Program.
+
+  Later license versions may give you additional or different
+permissions.  However, no additional obligations are imposed on any
+author or copyright holder as a result of your choosing to follow a
+later version.
+
+  15. Disclaimer of Warranty.
+
+  THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
+APPLICABLE LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
+HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
+OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
+THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
+IS WITH YOU.  SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
+ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+  16. Limitation of Liability.
+
+  IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
+THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
+GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
+USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
+DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
+PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
+EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
+SUCH DAMAGES.
+
+  17. Interpretation of Sections 15 and 16.
+
+  If the disclaimer of warranty and limitation of liability provided
+above cannot be given local legal effect according to their terms,
+reviewing courts shall apply local law that most closely approximates
+an absolute waiver of all civil liability in connection with the
+Program, unless a warranty or assumption of liability accompanies a
+copy of the Program in return for a fee.
+
+              END OF TERMS AND CONDITIONS
+
+     How to Apply These Terms to Your New Programs
+
+  If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+  To do so, attach the following notices to the program.  It is safest
+to attach them to the start of each source file to most effectively
+state the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the program's name and a brief idea of what it does.>
+    Copyright (C) <year>  <name of author>
+
+    This program is free software: you can redistribute it and/or modify
+    it under the terms of the GNU General Public License as published by
+    the Free Software Foundation, either version 3 of the License, or
+    (at your option) any later version.
+
+    This program is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
+    GNU General Public License for more details.
+
+    You should have received a copy of the GNU General Public License
+    along with this program.  If not, see <http://www.gnu.org/licenses/>.
+
+Also add information on how to contact you by electronic and paper mail.
+
+  If the program does terminal interaction, make it output a short
+notice like this when it starts in an interactive mode:
+
+    <program>  Copyright (C) <year>  <name of author>
+    This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+    This is free software, and you are welcome to redistribute it
+    under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License.  Of course, your program's commands
+might be different; for a GUI interface, you would use an "about box".
+
+  You should also get your employer (if you work as a programmer) or school,
+if any, to sign a "copyright disclaimer" for the program, if necessary.
+For more information on this, and how to apply and follow the GNU GPL, see
+<http://www.gnu.org/licenses/>.
+
+  The GNU General Public License does not permit incorporating your program
+into proprietary programs.  If your program is a subroutine library, you
+may consider it more useful to permit linking proprietary applications with
+the library.  If this is what you want to do, use the GNU Lesser General
+Public License instead of this License.  But first, please read
+<http://www.gnu.org/philosophy/why-not-lgpl.html>.
