in reply to using the Modules

The documentation of the lib pragma says:
This is a small simple module which simplifies the manipulation of @INC at compile time. It is typically used to add extra directories to perl's search path so that later use or require statements will find modules which are not located on perl's default search path.
It is the recommended way of dealing with modules in a non-standard path.

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
