# @BLURB: Common functions and setup utilities for the LeechCraft app
# @DESCRIPTION:
# The leechcraft eclass contains a common set of functions and steps
# needed to build LeechCraft core or its plugins.
#
# Though this eclass seems to be small at the moment, it seems like a
# good idea to make all plugins inherit from it, since all plugins
# have mostly the same configuring/build process.
#
# Thanks for original eclass to Andrian Nord <NightNord@niifaq.ru>.
#
# Only EAPI >1 supported
