To get more narrative info about these "products", you should check out the Guided Tour (go back to the Lick Tcl homepage and press the Tour button). This page is just the "ftp server" for code I wrote or co-wrote.

Note: All my Tcl code requires the TclX extension. You can find most well-known Tcl extensions by following links at or, two great resources which every tcl hacker (newbie to grandmaster) should find useful. Don't even know what an "extension" is? "Getting Started" and similar materials at will tell you everything you need to know.


See the Infra1 directory for the infrastructure behind most of our production code.

TkGlim: GUI for Glimpse

I love glimpse but I hate remembering all the cmd line options. If you feel the same, try tkglim!
