SourceForge http://www.sf.net/ - aka [SF] - is an ambitious attempt to provide open source projects with freely available
source code , bug, and request management, mailing list support, software distribution,
and more.  The effort has over 20,000 projects at this time.

A number of As of mid August, 2001 the massive collaborative project support site at SourceForge [http://sourceforge.net/]/[https://sourceforge.net/] has (at least) 250 projects in (or using) Tcl and Tcl/Tk.  Some stay in the top downloads, or high-activity category.  This page is started because ''so many'' projects have been moving to SF.  To make the most of your own 
explorations of SF, you'll likely want to use [CVS]; before you start,
read "Introduction to SourceForge.net Project CVS Services"
[https://sourceforge.net/docman/display_doc.php?docid=768&group_id=1]".

Browse these projects from their trove list at:
