Git::SVN::Prompt - authentication callbacks for git-svn

my $cached_simple = SVN::Client::get_simple_provider();
my $git_simple = SVN::Client::get_simple_prompt_provider(\&simple, 2);

my $git_ssl = SVN::Client::get_ssl_server_trust_prompt_provider(
\&ssl_server_trust);
my $cached_cert = SVN::Client::get_ssl_client_cert_file_provider();
my $git_cert = SVN::Client::get_ssl_client_cert_prompt_provider(
\&ssl_client_cert, 2);
my $cached_cert_pw = SVN::Client::get_ssl_client_cert_pw_file_provider();

\&ssl_client_cert_pw, 2);
my $cached_username = SVN::Client::get_username_provider();
my $git_username = SVN::Client::get_username_prompt_provider(
\&username, 2);
my $ctx = new SVN::Client(
auth => [

]);
=head1 DESCRIPTION
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.
