Our core expertise and passion is dealing with legacy Perl code. Perl has been in widespread use for twenty years, and whether it's code you wrote yourself, a long time ago, or - more likely - code someone else wrote (also a long time ago), when you have to deal with code that's unfamiliar and not modern, there are a host of issues to resolve.
Peter has made a career out of helping people deal with legacy Perl code, starting with his book on the topic, "Perl Medic" (2004, Addison-Wesley) and continuing through many convention presentations. Consequently, he understands the problems that legacy code can cause and how to solve them.
When you encounter legacy Perl code and wonder where to start, call PSDT and we will help.
