=head1 NAME
rgit - Recursively execute a command on all the git repositories in a directory tree.
=head1 VERSION
Version 0.08
=head1 SYNOPSIS
rgit [-K|-I|-D|-V] [GIT_OPTIONS] COMMAND [COMMAND_ARGS]
=head1 DESCRIPTION
This utility recursively searches in a root directory (which may be the current working directory or - if it has been set - the directory given by the C<GIT_DIR> environment variable) for all git repositories, sort this list by the repository path, C<chdir> into each of them, and executes the specified git command.
For efficiency reasons, repositories located inside a bare repository or under the F<.git> directory of a work repository won't be searched for.
Moreover, those formats are substituted in the arguments before running the command :
=over 4
=item *
C<%n> with the current repository name.
=item *
C<%g> with the relative path (based from the root directory) to the current repository.
=item *
C<%G> with the absolute path to the current repository.
=item *
C<%w> with the relative path (based from the root directory) to the current repository's working directory.
=item *
C<%W> with the absolute path to the current repository's working directory.
=item *
C<%b> with a "bareified" relative path, i.e. C<%g> if this is a bare repository, and C<%w.git> otherwise.
=item *
C<%B> with an absolute version of the "bareified" path.
=item *
C<%R> with the absolute path to the root directory.
=item *
C<%%> with a bare C<%>.
=back
There are actually a few commands that are only executed once in the root directory : C<daemon>, C<gui>, C<help>, C<init> and C<version>.
For any of those, no format substitution is done.
You can specify which C<git> executable to use with the C<GIT_EXEC_PATH> environment variable.
=head1 COMMAND LINE SWITCHES
C<rgit> takes its options as the capital switches that comes before the git command.
It's possible to bundle them together.
They are removed from the argument list before calling C<git>.
=over 4
=item *
C<-K>
Keep processing on error.
The default policy is to stop whenever an error occured.
=item *
C<-I>
Enables interactive mode when the standard input is a tty.
Requires L<Term::ReadKey> to be installed.
This lets you choose interactively what to do when one of the commands returns a non-zero status.
=item *
C<-D>
Outputs diagnostics.
=item *
C<-V>
Outputs the version.
=back
=head1 EXAMPLES
Execute C<git gc> on all the repositories below the current directory :
rgit gc
Tag all the repositories with their name :
rgit tag %n
Add a remote to all repositories in "/foo/bar" to their bare counterpart in C<qux> on F<host> :
GIT_DIR="/foo/bar" rgit remote add host git://host/qux/%b
