[nSLUG] Any Perl Experience around?

Off the top of my head, are the classification codes:

/ (Blue)
* (Lime)
~ (Magenta)

...because I cannot remember there being more symbols but I do recall more
colourization than four.  And my test directory, used colour more often
within the types than the use of the codes (except for the directory
marking which was probably the same).

At any rate, I can think of a Case logic within the string (wherever it may
be) to identify the class code.  Not sure how that lays out on paper though.

Looks simpler at this point.
