Just fixed it, I renamed etp-gc.tcl to etp-gc-procs.tcl and the comments appear now. Altered them to be centered and changed the Blah Blah think to just "Add a Comment".

All is well, thanks Dave for getting me to retry, taking a closer look and documenting what I did. Thanks Tilmann for getting me on the right track with the -procs.tcl thing.

This has been vexing me for a while, but it hasn't really been needed til now...

THANKS!
