# svg_convertPngToDm.sh -- This function standardize production of
40f83f
# display managers (e.g., Gdm and Kdm). This function copies all files
40f83f
# needed into a temporal directory, realize expansion of translation
40f83f
# markers and packs all the files into a tar.gz package that is used
40f83f
# for installation. This function must be used as last-rendition
40f83f
# action for Gdm and Kdm directory specific base-rendition actions.
