#
# Usage: include this file in your cdbs debian/rules file and define the
#        following variables:
#
#        MOZ_EXTENSION_PKG (OPTIONAL):
#        	if defined the given binary package name is used to ship this
#        	xpi; otherwise the first binary package listed in debian/control
#        	is used
#
#        MOZ_XPI_FILE (OPTIONAL):
#        	if defined the given .xpi file is used; otherwise we try to
#        	guess one using wildcard (*.xpi)
#
#        MOZ_XPI_EMID (OPTIONAL):
#        	if defined the given id is used to determine the link name
#        	in the firefox extensions directory. if not defined we try
#        	our best to extract the em:id from the install.rdf file shipped
#        	by any xpi
#
#        MOZ_XPI_BUILD_COMMAND (OPTIONAL):
#               if defined the given command will be run _before_ the extension
#               gets packaged up the standard .xpi way. Thus, the build command
#               should produce an .xpi in top level directory. Note: If this
#               command is specified, all .xpi files in the top level directory
#               will be removed during |clean|. If the xpi file will not be
#               build from source, you have to set this variable to nothing.
#
#        MOZ_XPI_MOZILLA_EXTRA_DIRS (OPTIONAL):
#               XXX: implement this!
#               defines extra directories to link the extension in.
#               usually xpi.mk creates the right links based on targetApplication
#               parsed in install.rdf; if you need more directories, use this.
#
#        MOZ_XPI_DOCUMENTED_LICENSE_FILES (OPTIONAL):
#               defines extra license files which need to be excluded during
#               the installation of the XPI file to the packaging tree. When
#               using parameter, be sure that you documented _all_ excluded
#               license files in debian/copyright appropriately. If not defined
#               the common license file names are tried.
#
#        Deprecated variables:
#
#        MOZ_XPI_MOZILLA_DIRS /deprecated/ (OPTIONAL/NODEFAULT - see "Note:"):
#               defines in which directories to create links for this extension.
#               the default is "firefox-addons", which means that
#               the extension will be linked appropriately to the
#               /usr/lib/firefox-addons/extensions directory.
#               '''Note''': this variable is deprecated and will go away; the
#               default is already empty; if you still need this variable, migrate
#               your code to MOZ_XPI_MOZILLA_EXTRA_DIRS
