| =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 | ||||
