The following are examples of pl_syscolors.d.
This is a simple script to trace the flow of Perl subroutines and system
calls made, and renders the output in color ("colour") using terminal
escape sequences (which you can tweak by modifying the script).
Here it traces the example program, Code/Perl/func_abc.pl.
WARNING: This output is full of terminal escape sequences, so if you are
trying to view this through an editor or web browser - it may look awful.
Try viewing this using "more" (although, depending on your terminal, it
still may look awful).

If the colors don't suit you (or you'd rather HTML colored output), it
should be trivial to modify the script to do so.
