Well where should links be provided to? If you give someone the link to the PerlRE page or PCRE page they will likely be confused. The PerlRE page contains tons of information that is specific to perl, and the PCRE man page is more about the C API than the actual regex. So where exactly should links be provided to? The basic regex, that someone who doesn't have the knowledge to look up PCRE would need help with, can easily be found by searching google for "regex tutorial." Not to mention the fact that there is a $regex and $regsub tutorial on mircscripts.org
