-#
-# Leave the variable UNSET if necko-wifi support should not be available.

-# Set the variable to any value if the use flag should exist but not be default-enabled.

-# @DESCRIPTION:
-# Set this variable before the inherit line, when an ebuild needs to provide

-# is missing.

-#
-# Leave the variable UNSET if gtk3 support should not be optionally available.
-# Set the variable to "enabled" if the use flag should be enabled by default.
-# Set the variable to any value if the use flag should exist but not be default-enabled.
-# If gtk+:3 is to be the standard toolkit, do not use this and instead use
-# MOZCONFIG_OPTIONAL_GTK2ONLY.
-
-# @ECLASS-VARIABLE: MOZCONFIG_OPTIONAL_GTK2ONLY
-# @DESCRIPTION:
-# Set this variable before the inherit line, when an ebuild can provide

-#
-# Note that this option conflicts directly with MOZCONFIG_OPTIONAL_GTK3, both
-# variables cannot be set at the same time and this variable will be ignored if
-# MOZCONFIG_OPTIONAL_GTK3 is set.
-#
-# Leave the variable UNSET if gtk2-only support should not be available.

-#
