+# to provide a single common place for the common mozilla engine compoments.
+#
+# The eclass provides all common dependencies as well as common use flags.
+#
+# Some use flags which may be optional in particular mozilla packages can be
+# supported through setting eclass variables.
+#
+# This eclass inherits mozconfig helper functions as defined in mozcoreconf-v3,
+# and so ebuilds inheriting this eclass do not need to inherit that.

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

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