# @BLURB: the new mozilla common configuration eclass for FF33 and newer, v5
# @DESCRIPTION:
# This eclass is used in mozilla ebuilds (firefox, thunderbird, seamonkey)
# 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.

# @ECLASS-VARIABLE: MOZCONFIG_OPTIONAL_WIFI
# @DESCRIPTION:
# Set this variable before the inherit line, when an ebuild needs to provide
# optional necko-wifi support via IUSE="wifi".  Currently this would include
# ebuilds for firefox, and potentially seamonkey.
#
# Leave the variable UNSET if necko-wifi support should not be 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.

# @ECLASS-VARIABLE: MOZCONFIG_OPTIONAL_JIT
# @DESCRIPTION:
# Set this variable before the inherit line, when an ebuild needs to provide
# optional necko-wifi support via IUSE="jit".  Currently this would include
# ebuilds for firefox, and potentially seamonkey.
#
# Leave the variable UNSET if optional jit support should not be 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.
