# 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.
