# @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.
