-#
-# This Makefile fragment provides boilerplate code for standard naming
-# conventions for handling per-package build options.
-#
-# Before including this file, the following variables can be defined:
-#
-# PKG_SUPPORTED_OPTIONS (must be defined)
-# This is a list of build options supported by the package.
-# This variable should be set in a package Makefile. E.g.,
-#
-# PKG_SUPPORTED_OPTIONS= kerberos ldap ssl
-#
-# PKG_OPTION_VAR (must be defined)
-# The variable the user can set to enable or disable
-# options specifically for this package.
-#
-# PKG_SUGGESTED_OPTIONS (defaults to empty)
-# This is a list of build options which are enabled by default.
-#
-# PKG_OPTION_LEGACY_VARS
-# This is a list of USE_VARIABLE:option pairs that
-# map legacy /etc/mk.conf variables to their option
-# counterparts.
-#
-#
-# Optionally, the user may define the following variables in /etc/mk.conf:
-#
-# PKG_DEFAULT_OPTIONS
-# This variable can be used to override default
-# options for every package. Options listed in this
-# variable will be enabled in every package that
-# supports them. If you prefix an option with `-',
-# it will be disabled in every package.
-#
-# ${PKG_OPTIONS_VAR}
-# This variable can be used to override default
-# options and options listed in PKG_DEFAULT_OPTIONS.
-# The syntax is the same as PKG_DEFAULT_OPTIONS.
-#
-# After including this file, the following variables are defined:
-#
-# PKG_OPTIONS
-# This is the list of the selected build options, properly
-# filtered to remove unsupported and duplicate options.
-#
-# Example usage:
-#
-# -------------8<-------------8<-------------8<-------------8<-------------
-# PKG_SUPPORTED_OPTIONS= foo ldap sasl
-# PKG_SUGGESTED_OPTIONS= foo
-# PKG_OPTIONS_LEGACY_VARS+= WIBBLE_USE_OPENLDAP:ldap
-# PKG_OPTIONS_LEGACY_VARS+= WIBBLE_USE_SASL2:sasl
