-CGI paths are converted into action names using cgi_action (below.)
-
-A path such as C<root/cgi-bin/hlagh/bar.cgi> will get the private path
-C<foo/CGI_hlagh_bar_cgi>, for controller Foo, with the C</>s converted to C<_>s
-and prepended with C<CGI_>, as well as all non-word characters converted to
-C<_>s. This is because L<Catalyst> action names can't have non-word characters
-in them.
