# This script get the various breeze icons used by an application
# and output a Qt plugin that can be statically linked using the
# official Qt plugin system. It makes applications more portable
# since they no longer require a valid icon theme to be installed.
#
# This is a *fallback* for platforms without an icon theme or with
# incomplete icon themes at the cost of a larger binary.
