This Contrib is somewhat usual because it contains libraries which are not under the TWiki namespace. See: http://twiki.org/cgi-bin/view/Codev/AddCGIpmToTWikiCore CgiContrib contains a "frozen" version of Perl's CGI distribution. We decided to add it to TWiki because the CGI maintainer, Lee Johnson, has informed us that there'll be a couple of changes which might affect compatibility. In fact, we have had some support questions caused by changes in CGI while a first incompatible change has been available only on github, neither the CPAN version nor the versions shipped with Linux distributions were affected. Though compatibility is highly-valued in the TWiki community, we appreciate the effort and play safe by moving TWiki out of the way of GCI's development. Occasionally the TWiki team will review changes in CGI and rebase this Contrib accordingly. The directories data and lib/TWiki have been added to the CGI distribution for TWiki's contrib bookkeeping. The examples directory from the CGI distribution has not been included here. Yours, Harald.Joerg@arcor.de and TWiki Contributors
