+=head1 NAME
+
+webcheckout - check out repositories referenced on a web page
+
+=head1 SYNOPSIS
+
+B<webcheckout> [options] url [destdir]
+
+=head1 DESCRIPTION
+
+B<webcheckout> downloads an url and parses it, looking for version control 
+repositories referenced by the page. It checks out each repository into
+a subdirectory of the current directory, using whatever VCS program is
+appropriate for that repository (git, svn, etc).
+
+The information about the repositories is embedded in the web page using
+the rel=vcs microformat, which is documented at
+<http://kitenet.net/~joey/rfc/rel-vcs/>.
+
+If the optional destdir parameter is specified, VCS programs will be asked
+to check out repositories into that directory. If there are multiple
+repositories to check out, each will be checked out into a separate
+subdirectory of the destdir.
+
+=head1 OPTIONS
+
+=over 4
+
+=item -a, --auth
+
+Prefer authenticated repositories. By default, webcheckout will use
+anonymous repositories when possible. If you have an account that
+allows you to use authenticated repositories, you might want to use this
+option.
+
+=item -n
+
+Do not actually check anything out, just print out the commands that would
+be run to check out the repositories.
+
+=item -q
+
+Quiet mode. Do not print out the commands being run. (The VCS commands
+may still be noisy however.)
