The first book to explain how to understand, maintain, update, and improve existing Perl code
° Perl is especially susceptible to maintenance problems, because of its flexible style and ad hoc origins
° Author uses a medical theme throughout, playing off the similarities of doctoring or healing broken code
° Contains the most comprehensive treatment of testing Perl programs ever published, as well as the most comprehensive discussion of Perl version differences
Bring new power, performance, and scalability to your existing Perl code!
If you've ever inherited Perl code that's hard to maintain, if you write Perl code others will read, if you want to write code that'll be easier for you to maintain, the book that comes to your rescue is Perl Medic.
If you code in Perl, you need to read this book.–Adam Turoff, Technical Editor, The Perl Review.
Scott's explanations of complex material are smooth and deceptively simple. He knows his subject matter and his craft-he makes it look easy. Scott remains relentless practical-even the 'Analysis' chapter is filled with code and tests to run.–Dan Livingston, author of several computer books including Advanced Flash 5: Actionscript in Action
