# These variables are used in port makefiles to define the options for a port.
#
# OPTIONS_DEFINE		- List of options this port accepts
# OPTIONS_DEFINE_${ARCH}	- List of options this port accepts 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_EXCLUDE_${OPSYS}	- List of options unsupported on a given ${OPSYS}
# OPTIONS_EXCLUDE_${OPSYS}_${OSREL:R} - List of options unsupported on a given
#				  ${OPSYS} and major version (11/12/13...)
# 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
#
#
# These variables are strictly informational (read-only).  They indicate the
# current state of the selected options; they are space-delimited lists.
#
# SELECTED_OPTIONS		- list of options set "on"
# DESELECTED_OPTIONS		- list of options set "off"
#
#
# 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.

#				the QMAKE_ARGS.
# ${opt}_QMAKE_OFF		When option is disabled, it will add its content to
#				the QMAKE_ARGS.
#
# ${opt}_MESON_ON		When option is enabled, it will add its
#				content to MESON_ARGS.
# ${opt}_MESON_OFF		When option is disabled, it will add its
#				content to MESON_ARGS.
#
# ${opt}_MESON_TRUE		Will add to MESON_ARGS:
#				Option enabled	-D${content}=true

#				Option disabled	-D${content}=enabled
#
# ${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
#
# For each of the depends target PKG FETCH EXTRACT PATCH BUILD LIB RUN,
# defining ${opt}_${deptype}_DEPENDS will add its content to the actual
# dependency when the option is enabled.  Defining
# ${opt}_${deptype}_DEPENDS_OFF will add its content to the actual dependency
# when the option is disabled.
#
# For each of the variables in _OPTIONS_FLAGS below, defining
# ${opt}_${variable} will add its content to the actual variable when the
# option is enabled.  Defining ${opt}_${variable}_OFF will add its content to
# the actual variable when the option is disabled.

##
# Set all the options available for the ports, beginning with the
# global ones and ending with the ones decided by the maintainer.
