To make the latest source code slightly more accessible, and able to accept patches (pull requests) more easily, I have converted the SVN repository for Tcl::pTk on SourceForge (https://sourceforge.net/p/perl-tcl-ptk/code/) to a Git repository, and have published it to GitHub:
https://github.com/chrstphrchvz/perl-tcl-ptk I’ll make sure it shows up on metaCPAN with the next release. Christopher A. Chavez
