This is extracted from MDK::Common, a helper library that extends perl capabilities for very common use when programming perl, especially with functional style programming (but what other style one could decently adopt? ;p).

This extract is provided here because only Mandrake distro includes the whole MDK::Common, so you’re not obliged to install it.

That said, if you’re a perl programmer, I strongly advice you to have a look at this library and use it, it would dramatically increase the efficiency and readability of your perl programs.

Go to google and type in "perl-MDK-Common" if interested.
