# Please note: we can't name the man pages
# ocf:heartbeat:<name>. Believe me, I've tried. It looks like it
# works, but then it doesn't. While make can deal correctly with
# colons in target names (when properly escaped), it royally messes up
# when it is deals with _dependencies_ that contain colons. See Bug
# 12126 on savannah.gnu.org. But, maybe it gets fixed soon, it was
# first reported in 1995 and added to Savannah in in 2005...
