# This is a convenience script for bumping Amarok's plugin framework version
# in the various engine desktop files and in pluginmanager.h.
#
# The script should be run once before each release, in order to ensure that
# no old and perhaps incompatible engines are getting loaded. After running, don't
# forget to commit and push. The script must be started from the amarok/ folder.
