Documentation:
Alist of regular expressions matching special library directories.
When listing routine source locations, IDLWAVE gives a short hint where
the file defining the routine is located. By default it lists `SystemLib'
for routines in the system library `!DIR/lib' and `Library' for anything
else. This variable can define additional types. The car of each entry
is a regular expression matching the file name (they normally will match
on the path). The cdr is the string to be used as identifier. Max 10
chars are allowed.

You can customize this variable.
