The script slicer2/Scripts/comment.tcl will automatically place comment headers above all procedures in all Tcl source code files. Please run this script regularly, and then place descriptions of the procedures in the comment headers. (This script also places the copyright in all files, including those in the Base/cxx directory.)

These comments are used to generate documentation for this website. See the link Tcl Source Code in the Developer's Guide. The comment headers can be written in pseudo-html. See slicer2/Base/tcl/tcl-main/Comment.tcl for an example.
