# $FreeBSD$
#
# These variables are used in port makefiles to define the options for a port.
#
# OPTIONS_DEFINE		- List of options this ports accept
# OPTIONS_DEFINE_${ARCH}	- List of options this ports accept and are
#				  specific to ${ARCH}
# OPTIONS_DEFAULT		- List of options activated by default
# OPTIONS_DEFAULT_${ARCH}	- List of options activated by default for a
#				  given arch
#
# ${OPTION}_DESC		- Description of the ${OPTION}
#
# OPTIONS_SINGLE		- List of single-choice grouped options: 1 and
#				  only 1 among N
# OPTIONS_RADIO			- List of radio-choice grouped options: 0 or 1
#				  among N
# OPTIONS_MULTI			- List of multiple-choice grouped options: at
#				  least 1 among N
# OPTIONS_GROUP			- List of group-choice grouped options: 0 or
#				  more among N
#
# OPTIONS_SINGLE_${NAME}	- List of OPTIONS grouped as single choice (for
#				  the single named as ${NAME} as defined in
#				  OPTIONS_SINGLE)
# OPTIONS_RADIO_${NAME}		- List of OPTIONS grouped as radio choice (for
#				  the radio named as ${NAME} as defined in
#				  OPTIONS_RADIO)
# OPTIONS_MULTI_${NAME}		- List of OPTIONS grouped as multiple-choice
#				  (for the multi named as ${NAME} as defined in
#				  OPTIONS_MULTI)
# OPTIONS_GROUP_${NAME}		- List of OPTIONS grouped as group-choice (for
#				  the group named as ${NAME} as defined in
#				  OPTIONS_GROUP)
#
# OPTIONS_EXCLUDE		- List of options unsupported (useful for slave ports)
# OPTIONS_EXCLUDE_${ARCH}	- List of options unsupported on a given ${ARCH}
# OPTIONS_EXCLUDE_${OPSYS}	- List of options unsupported on a given ${OPSYS}
# OPTIONS_SLAVE			- This is designed for slave ports, it removes an
#				  option from the options list inherited from the
#				  master port and it always adds it to PORT_OPTIONS
#				  meaning activated
#
# These variables can be used in make.conf to configure options.  They are
# processed in the order listed below, i.e. later variables override the effects
# of previous variables.  Options saved using the options dialog are processed
# right before OPTIONS_SET_FORCE.  When building a port a dialog to configure
# options will only appear if there are new options, i.e. options which have not
# been configured before either using the option dialog in a previous build or
# using the variables below.  You can force the dialog to appear by running
# "make config".
#
# OPTIONS_SET			- List of options to enable for all ports.
# OPTIONS_UNSET			- List of options to disable for all ports.
# ${OPTIONS_NAME}_SET		- List of options to enable for a specific port.
# ${OPTIONS_NAME}_UNSET		- List of options to disable for a specific port.
#
# OPTIONS_SET_FORCE		- List of options to enable for all ports.
# OPTIONS_UNSET_FORCE		- List of options to disable for all ports.
# ${OPTIONS_NAME}_SET_FORCE	- List of options to enable for a specific port.
# ${OPTIONS_NAME}_UNSET_FORCE
#				- List of options to disable for a specific port.
#
# These variables can be used on the command line. They override the effects of
# the make.conf variables above.
#
# WITH				- Set options from the command line
# WITHOUT			- Unset options from the command line
#
#
# The following knobs are there to simplify the handling of OPTIONS in simple
# cases :
#
# OPTIONS_SUB			When defined it will add to PLIST_SUB:
#				Option enabled  ${opt}=""
#				Option disabled ${opt}="@comment "
#
# ${opt}_CONFIGURE_ON		When option is enabled, it will add its content to
#				the CONFIGURE_ARGS.
# ${opt}_CONFIGURE_OFF		When option is disabled, it will add its content to
#				the CONFIGURE_ARGS.
# ${opt}_CONFIGURE_ENABLE	Will add to CONFIGURE_ARGS:
#				Option enabled  --enable-${content}
#				Option disabled --disable-${content}
# ${opt}_CONFIGURE_WITH		Will add to CONFIGURE_ARGS:
#				Option enabled  --with-${content}
#				Option disabled --without-${content}
#
# ${opt}_CMAKE_ON		When option is enabled, it will add its content to
#				the CMAKE_ARGS.
# ${opt}_CMAKE_OFF		When option is disabled, it will add its content to
#				the CMAKE_ARGS.
#
# ${opt}_QMAKE_ON		When option is enabled, it will add its content to
#				the QMAKE_ARGS.
# ${opt}_QMAKE_OFF		When option is disabled, it will add its content to
#				the QMAKE_ARGS.
#
# ${opt}_IMPLIES		When opt is enabled, options named in IMPLIES will
#				get enabled too.
# ${opt}_PREVENTS		When opt is enabled, if any options in PREVENTS are
#				also enabled, it will produce an error.
# ${opt}_PREVENTS_MSG		Provides a message explaining why the options
#				cannot be selected together.
#
# ${opt}_USE=	FOO=bar		When option is enabled, it will  enable
#				USE_FOO+= bar
#				If you need more than one option, you can do
#				FOO=bar,baz and you'll get USE_FOO=bar baz
# ${opt}_USE_OFF=	FOO=bar	When option is disabled, it will enable
#				USE_FOO+= bar
#
# ${opt}_VARS=	FOO=bar		When option is enabled, it will set
#				FOO= bar
# ${opt}_VARS=	FOO+=bar	When option is enabled, it will append
#				FOO+= bar
# ${opt}_VARS_OFF=    FOO=bar	When option is disabled, it will set
#				FOO= bar
# ${opt}_VARS_OFF=    FOO+=bar	When option is disabled, it will append
#				FOO+= bar
