I'd write a logging module that sends things to syslog, event-log or a old-fashioned text-log file depending on the OS.
Think of DBI-for-logging, with DBD-like modules for each OS.
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
