Hi,

Whats difference between "use" and "require" in perl?

use is done at ‘compile-time’ and require is done at ‘run-time’ (ie can conditionally load modules)

More...

use is a pre-built in function in perl to Imports some semantics into the current package from the named module, generally by aliasing certain subroutine or variable names into your package such as..

* use Module VERSION LIST

* use Module VERSION
* use Module LIST
* use Module
* use VERSION
