# Maintainer note for OPTION handling:
# To set additional option use
#    PORT_OPTIONS+=
# To unset an OPTION, even the OPTION is set in OPTIONSFILE use
#    WITHOUT_MODULES+=
#  Using OPTIONS_EXCLUDE and OPTIONS_OVERRIDE do not work as expected
#  if the OPTION is enabled by the user, therefore we calculate
#  them in bsd.apache.mk with help of WITHOUT_MODULES
#  The other methode is to set IGNORE's and force the user to adjust OPTIONS
