=head1 NAME

SVN::RaWeb::Light - Lightweight and Fast Browser for a URLed Subversion 



    use SVN::RaWeb::Light;

    my $app = SVN::RaWeb::Light->new(
        'url' => "svn://",



SVN::RaWeb::Light is a class implementing a CGI script for browsing
a Subversion repository given as a URL, and accessed through the Subversion
Repository-Access layer. To use it, install the module (using CPAN or by
copying it to your path) and write the CGI script given in the SYNOPSIS
with the URL to the repository passed as the C<'url'> parameter to 
the constructor.

To use it just fire up a web-browser to the URL of the script. Note that
you can pass the rev CGI parameter to designate a revision of the repository
to browse instead of HEAD. This rev will be preserved to subsequent URLs
that you browse. For example:
will browse the trunk in revision 20.
