-Git::SVN::Editor - commit driver for "git svn set-tree" and dcommit
-
-=head1 SYNOPSIS
-
-	use Git::SVN::Editor;
-	use Git::SVN::Ra;
-
-	my $ra = Git::SVN::Ra->new($url);
-	my %opts = (
-		r => 19,
-		log => "log message",
-		ra => $ra,
-		config => SVN::Core::config_get_config($svn_config_dir),
-		tree_a => "$commit^",
-		tree_b => "$commit",
-		editor_cb => sub { print "Committed r$_[0]\n"; },
-		mergeinfo => "/branches/foo:1-10",
-		svn_path => "trunk"

-
-=head1 DESCRIPTION
-
-This module is an implementation detail of the "git svn" command.
-Do not use it unless you are developing git-svn.
-
-This module adapts the C<SVN::Delta::Editor> object returned by
-C<SVN::Delta::get_commit_editor> and drives it to convey the
-difference between two git tree objects to a remote Subversion
-repository.
-
-The interface will change as git-svn evolves.
-
-=head1 DEPENDENCIES
-
-Subversion perl bindings,
-the core L<Carp> module,
-and git's L<Git> helper module.
-
-C<Git::SVN::Editor> has not been tested using callers other than
-B<git-svn> itself.
-
-=head1 SEE ALSO
-
-L<SVN::Delta>,
-L<Git::SVN::Fetcher>.
-
-=head1 INCOMPATIBILITIES
-
-None reported.
-
-=head1 BUGS
-
-None.

-=head1 DESCRIPTION
-
-This is a subclass of C<SVN::Delta::Editor>, which means it implements
-callbacks to act as a consumer of Subversion tree deltas.  This
-particular implementation of those callbacks is meant to store
-information about the resulting content which B<git svn fetch> could
-use to populate new commits and new entries for F<unhandled.log>.
-More specifically:
-
-=over
-
-=item * Additions, removals, and modifications of files are propagated
-to git-svn's index file F<$GIT_DIR/svn/$refname/index> using
-B<git update-index>.
-
-=item * Changes in Subversion path properties are recorded in the
-C<dir_prop> and C<file_prop> fields (which are hashes).
-
-=item * Addition and removal of empty directories are indicated by
-entries with value 1 and 0 respectively in the C<empty> hash.
-
-=item * Paths that are present but cannot be conveyed (presumably due
-to permissions) are recorded in the C<absent_file> and
-C<absent_dirs> hashes.  For each key, the corresponding value is
-a list of paths under that directory that were present but
-could not be conveyed.
-
-=back
-
-The interface is unstable.  Do not use this module unless you are
-developing git-svn.
-
-=head1 DEPENDENCIES
-
-L<SVN::Delta> from the Subversion perl bindings,
-the core L<Carp> and L<File::Basename> modules,
-and git's L<Git> helper module.
-
-C<Git::SVN::Fetcher> has not been tested using callers other than
-B<git-svn> itself.
-
-=head1 SEE ALSO
-
-L<SVN::Delta>,
-L<Git::SVN::Editor>.
-
-=head1 INCOMPATIBILITIES
-
-None reported.
-
-=head1 BUGS
-
-None.

-=head1 NAME
-
-Git::SVN::Memoize::YAML - store Memoized data in YAML format
-
-=head1 SYNOPSIS
-
-    use Memoize;
-    use Git::SVN::Memoize::YAML;
-
-    tie my %cache => 'Git::SVN::Memoize::YAML', $filename;
-    memoize('slow_function', SCALAR_CACHE => [HASH => \%cache]);
-    slow_function(arguments);
-
-=head1 DESCRIPTION
-
-This module provides a class that can be used to tie a hash to a
-YAML file.  The file is read when the hash is initialized and
-rewritten when the hash is destroyed.
-
-The intent is to allow L<Memoize> to back its cache with a file in
-YAML format, just like L<Memoize::Storable> allows L<Memoize> to
-back its cache with a file in Storable format.  Unlike the Storable
-format, the YAML format is platform-independent and fairly stable.
-
-Carps on error.
-
-=head1 DIAGNOSTICS
-
-See L<YAML::Any>.
-
-=head1 DEPENDENCIES
-
-L<YAML::Any> from CPAN.
-
-=head1 INCOMPATIBILITIES
-
-None reported.
-
-=head1 BUGS
-
-The entire cache is read into a Perl hash when loading the file,
-so this is not very scalable.

-# v3.1 layout (auto migrated):
-#            - .rev_db => .rev_db.$UUID, .rev_db will remain as a symlink
-#              for backwards compatibility

-#            - this is only created for newly multi-init-ed
-#              repositories.  Similar in spirit to the

-# v5 layout: .rev_db.$UUID => .rev_map.$UUID

-#            - use xxd -c24 < .rev_map.$UUID to view and debug
-#            - This is a one-way migration, repositories updated to the
-#              new format will not be able to use old git-svn without
-#              rebuilding the .rev_db.  Rebuilding the rev_db is not
-#              possible if noMetadata or useSvmProps are set; but should

-This module is an implementation detail of the "git svn" command.
-It implements git-svn's authentication policy.  Do not use it unless
-you are developing git-svn.
-
-The interface will change as git-svn evolves.

-=head1 NAME
-
-Git::SVN::Ra - Subversion remote access functions for git-svn
-
-=head1 SYNOPSIS
-
-    use Git::SVN::Ra;
-
-    my $ra = Git::SVN::Ra->new($branchurl);
-    my ($dirents, $fetched_revnum, $props) =
-        $ra->get_dir('.', $SVN::Core::INVALID_REVNUM);
-
-=head1 DESCRIPTION
-
-This is a wrapper around the L<SVN::Ra> module for use by B<git-svn>.
-It fills in some default parameters (such as the authentication
-scheme), smooths over incompatibilities between libsvn versions, adds
-caching, and implements some functions specific to B<git-svn>.
-
-Do not use it unless you are developing git-svn.  The interface will
-change as git-svn evolves.
-
-=head1 DEPENDENCIES
-
-Subversion perl bindings,
-L<Git::SVN>.
-
-C<Git::SVN::Ra> has not been tested using callers other than
-B<git-svn> itself.
-
-=head1 SEE ALSO
-
-L<SVN::Ra>.
-
-=head1 INCOMPATIBILITIES
-
-None reported.
-
-=head1 BUGS
-
-None.

-=head1 NAME
-
-Git::SVN::Utils - utility functions used across Git::SVN
-
-=head1 SYNOPSIS
-
-    use Git::SVN::Utils qw(functions to import);
-
-=head1 DESCRIPTION
-
-This module contains functions which are useful across many different
-parts of Git::SVN.  Mostly it's a place to put utility functions
-rather than duplicate the code or have classes grabbing at other
-classes.
-
-=head1 FUNCTIONS
-
-All functions can be imported only on request.
-
-=head3 fatal
-
-    fatal(@message);
-
-Display a message and exit with a fatal error code.
-
-=cut
-
-# Note: not certain why this is in use instead of die.  Probably because
-# the exit code of die is 255?  Doesn't appear to be used consistently.
-sub fatal (@) { print STDERR "@_\n"; exit 1 }

-=head3 can_compress
-

-=head3 canonicalize_path
-

-Converts $path into a canonical form which is safe to pass to the SVN
-API as a file path.
