[gentoo-commits] gentoo-x86 commit in eclass: gdesklets.eclass

  Modified:             gdesklets.eclass
  Log:
  Simplified the eclass, since the rules for desklet and control submission have become much more standardized recently (http://gdesklets.de/index.php?q=node/2).  This also means that we will no longer support sensors and sensor-based desklets.  No more desklets that do not heed these rules will be put into portage.

+# @ECLASS: gdesklets.eclass
+# @MAINTAINER:
+# gdesklets@g.o
+# @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)
 #
-# Usage:
-# As a writer for an ebuild for gDesklets, you should set a few things:
+# 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).
 #
-#	DESKLET_NAME: The name of the desklet.
-#	DOCS: Anything (like a README) that should be dodoc'd.
-#	S: *Optional* The package's base directory.
-#		Usually ${WORKDIR}/${DESKLET_NAME} if it was packaged
-#		correctly (hence, this is the default).
-# 	RDEPEND: *Optional* Set if the desklet requires a minimum version
-#		of gDesklets greater than 0.34 or other packages.
+# Original authors:	Joe Sapp <nixphoeni@g.o>
+#			Mike Gardiner <obz@g.o>
+
+# @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.
