Code Colorizer-2.4.0

Fixed a problem for PERL that caused the forward slash in $/ to be recognized as the start of a regular expression.

I created a master module that consolidates the code for handling: colorize the selected text, colorize the fragment at the cursor, and colorize the entire document. The individual routines call the master with arguments that specify the desired language and mode. This consolidates the driver code so that there is one copy. The result is a smaller package with less code.
