in reply to mod_perl and legacy code

Unless RT needs versions of other modules that are mutually incompatible with the needs of already running applications, there should be no problem and even then with some juggling of use lib .. this can be made to work.

Legacy code will probably need to be run under Apache::Registry. The mod_perl site has this documentation: Guide to Porting.

A program should be light and agile, its subroutines connected like a string of pearls. The spirit and intent of the program should be retained throughout. There should be neither too little or too much, neither needless loops nor useless variables, neither lack of structure nor overwhelming rigidity." - The Tao of Programming, 4.1 - Geoffrey James
