Purpose: to document the use of another of the magic names in Tcl.
What is its purpose?
What is its format?
What are some good reasons to set it?
* test a package without installing.
What else?
PT 20-Jul-2004 This environment variable is used to add directories to the Tcl package search path (the auto_path tcl global variable).
I like to keep all my local packages separate from the ActiveTcl installation that I use as a base. So I install all additional packages to a site-lib directory and then set TCLLIBPATH to this directory path. With this in place a [package require XYZ] command will search ActiveTcl and my site-lib directory for the most recent version of XYZ.
