# @BLURB: Installation functions for Desklets and Controls supported by gDesklets
# @DESCRIPTION:
# The gdesklets eclass provides a simple way to create ebuilds for
# globally installing desktop applets ("Desklets") and supporting code
# ("Controls") used in the gDesklets framework (provided by
# gnome-extra/gdesklets-core)
#
# This eclass assumes a package following the instructions at
# http://gdesklets.de/index.php?q=node/2 . Specifically, the package
# should be a Desklet or Control ONLY (and *not* a Sensor). You
# technically could have an ebuild that works around this limitation,
# but no new packages should be added to the tree that do this (mainly
# for ease of maintenance).
# @ECLASS-VARIABLE: DESKLET_NAME
# @DESCRIPTION:
# *Optional* The name of the Desklet, if the package is one. The
# default is to assume a Desklet with the name being ${PN} without the
# "desklet-" prefix.
# @ECLASS-VARIABLE: CONTROL_NAME
# @DESCRIPTION:
# *Optional* The name of the Control, if the package is one.
# @ECLASS-VARIABLE: DOCS
# @DESCRIPTION:
# Anything (like a README) that should be dodoc'd.
# @ECLASS-VARIABLE: SLOT
# @DESCRIPTION:
# Set only if the package is a Control and it provides a different
# interface (i.e. expands to a different install directory) than a
# previous version.
