# @FUNCTION: doicon
# @USAGE: doicon [options] <icons>

#    16 22 24 32 36 48 64 72 96 128 192 256 scalable
# -c, --context
#    defaults to "apps"

#    defaults to "hicolor"
#
# icons: list of icons
# @CODE
#
# example 1:
#    doicon foobar.png fuqbar.svg
#    results in: insinto /usr/share/pixmaps ; doins foobar.png fuqbar.svg
#
# example 2:
#    doicon -s 48 foobar.png fuqbar.png
#    results in: insinto /usr/share/icons/hicolor/48x48/apps ; doins foobar.png fuqbar.svg

	_iconins "$@"

#
# example 2:
#    newicon -s 48 foobar.png NEWNAME.png 
#    results in: insinto /usr/share/icons/hicolor/48x48/apps ; newins foobar.png NEWNAME.png
