Introduction to PERL expressions

This section has been split up into subsections based upon functionality, loosely based upon the Perl Reference Guide by Johan Vromans. This is a departure from the original Perl manual, which should simplify on-line browsing. If you have problems with this organization, blame me (rgs@cs.cmu.edu) rather than Larry.
