620 | Git::SVN::Ra - Subversion remote access functions for git-svn | |
621 | ||
622 | =head1 SYNOPSIS | |
623 | ||
624 | use Git::SVN::Ra; | |
625 | ||
626 | my $ra = Git::SVN::Ra->new($branchurl); | |
627 | my ($dirents, $fetched_revnum, $props) = | |
628 | $ra->get_dir('.', $SVN::Core::INVALID_REVNUM); | |
629 | ||
630 | =head1 DESCRIPTION | |
631 | ||
632 | This is a wrapper around the L<SVN::Ra> module for use by B<git-svn>. | |
633 | It fills in some default parameters (such as the authentication | |
634 | scheme), smooths over incompatibilities between libsvn versions, adds | |
635 | caching, and implements some functions specific to B<git-svn>. | |
636 | ||
637 | Do not use it unless you are developing git-svn. The interface will | |
638 | change as git-svn evolves. | |
639 | ||
640 | =head1 DEPENDENCIES | |
641 | ||
642 | Subversion perl bindings, | |
643 | L<Git::SVN>. | |
644 | ||
645 | C<Git::SVN::Ra> has not been tested using callers other than | |
646 | B<git-svn> itself. | |
647 | ||
