# This script is meant to be invoked from within a Makefile/Makefile.am

# in the install-data-local and uninstall-data sections. It handles the

# task of properly installing icons into the icon theme. It requires a

# few arguments to set up its environment, and a list of files to be

# installed. The format of the file list is critical:

#

# <category>,<local-src-file-name>

#

#   apps,music-player-banshee.svg

#   apps,music-player-banshee-16.png

#   apps,music-player-banshee-22.png

#

# <category> is the icon theme category, for instance, apps, devices,

# actions, emblems...

#

# <local-src-file-name> must have a basename in the form of:

#

#   proper-theme-name[-<SIZE>].<EXTENSION>

#

# Where <SIZE> should be either nothing, which will default to scalable

# or \-[0-9]{2}, which will expand to <SIZE>x<SIZE>. For example:

#

#   music-player-banshee-16.png

#

# The <SIZE> here is -16 and will expand to 16x16 per the icon theme spec

#

# What follows is an example Makefile.am for icon theme installation:

#

# ---------------

# theme=hicolor

# themedir=$(datadir)/icons/$(theme)

# theme_icons = \

#	apps,music-player-banshee.svg \

#	apps,music-player-banshee-16.png \

#	apps,music-player-banshee-22.png \

#	apps,music-player-banshee-24.png \

#	apps,music-player-banshee-32.png

#

# install_icon_exec = $(top_srcdir)/build/icon-theme-installer -t $(theme) -s $(srcdir) -d "x$(DESTDIR)" -b $(themedir) -m "$(mkinstalldirs)" -x "$(INSTALL_DATA)"

# install-data-local:

#	$(install_icon_exec) -i $(theme_icons)

#

#	uninstall-hook:

#		$(install_icon_exec) -u $(theme_icons)

#

#	MAINTAINERCLEANFILES = Makefile.in

#	EXTRA_DIST = $(wildcard *.svg *.png)

# ---------------

#

# Arguments to this program:

#

# -i         : Install

# -u         : Uninstall

# -t <theme> : Theme name (hicolor)

# -b <dir>   : Theme installation dest directory [x$(DESTDIR)] - Always prefix

#              this argument with x; it will be stripped but will act as a

#              placeholder for zero $DESTDIRs (only set by packagers)

# -d <dir>   : Theme installation directory [$(hicolordir)]

# -s <dir>   : Source directory [$(srcdir)]

# -m <exec>  : Command to exec for directory creation [$(mkinstalldirs)]

# -x <exec>  : Command to exec for single file installation [$(INSTALL_DATA)]

# <remainging> : All remainging should be category,filename pairs
