# KNOBS - A list of popular knobs and their descriptions
#
# $FreeBSD$
#
# Rules for adding knobs:
#
#  - Knob names must be 12 characters or less
#  - Knob descriptions must be 45 characters or less
#
#  - Naming knobs:
#      When a port has a lib-prefix (e.g.: libquicktime, libxine)
#      the lib-prefix should be stripped from the knob name
#     (e.g.: QUICKTIME, XINE).
#
# Keep this list sorted in alphabetical order.
