# @BLURB: eclass to ease managing of Sabayon split net-p2p/transmission
# @DESCRIPTION:
# This experimental eclass is to ease managing of split net-p2p/transmission
# for Sabayon.
# Its name contains a version that corresponds to net-p2p/transmission one,
# because the eclass will change often when needed to follow changes
# in Gentoo ebuild.

# @ECLASS-VARIABLE: E_TRANSM_TAIL
# @DESCRIPTION:
# "Tail" of package name. Can take value gtk+, qt4, etc. or can be empty.
# It shouldn't be modified.
E_TRANSM_TAIL=${PN#transmission}
E_TRANSM_TAIL=${E_TRANSM_TAIL#-}

# @FUNCTION: _transmission_is
# @DESCRIPTION:
# Function used to check which variant of Transmission are we working on.
# Argument should be one of these: (none), gtk+, qt4, daemon, cli, base.
# If argument is empty or omitted, true value means that it is
# net-p2p/transmission (metapackage).
# Consider it private.

	local what=$1
