-### What it is
-
-On of the many things that didn't quite get into the Common
-Lisp standard was how to get a Lisp to output its call stack
-when something has gone wrong. As such, each Lisp has
-developed its own notion of what to display, how to display
-it, and what sort of arguments can be used to customize it.
-`trivial-backtrace` is a simple solution to generating a
-backtrace portably. As of {today}, it supports Allegro Common
-Lisp, LispWorks, ECL, MCL, SCL, SBCL and CMUCL. Its
-interface consists of three functions and one variable:
-
- * print-backtrace
- * print-backtrace-to-stream
- * print-condition
- * \*date-time-format\*
-
-You can probably already guess what they do, but they are
-described in more detail below.

-    announcements, questions, patches, bug reports, and so

-### Where is it
-
-A [git][] repository is available using
-
-    git clone http://common-lisp.net/project/trivial-backtrace/trivial-backtrace.git
-    
-The [darcs][] repository is still around but is **not** being updated.
-The command to get it is below:
-
-    ;;; WARNING: out of date
-    darcs get http://common-lisp.net/project/trivial-backtrace/
-
-trivial-backtrace is also [ASDF installable][asdf-install].
-Its CLiki home is right [where][cliki-home] you'd expect.
-
-There's also a handy [gzipped tar file][tarball].
