-# @FUNCTION: mozconfig_install_prefs
-# @DESCRIPTION:
-# Set preferences into the prefs.js file specified as a parameter to
-# the function.  This sets both some common prefs to all mozilla
-# packages, and any prefs that may relate to the use flags administered
-# by mozconfig_config().
-#
-# Call this within src_install() phase, after copying the template
-# prefs file (if any) from ${FILESDIR}
-#
-# Example:
-#
-# inherit mozconfig-v6.46
-#
-# src_install() {
-# 	cp "${FILESDIR}"/gentoo-default-prefs.js \
-#	"${BUILD_OBJ_DIR}/dist/bin/browser/defaults/preferences/all-gentoo.js"  \
-#	|| die
-#
-# 	mozconfig_install_prefs \
-#	"${BUILD_OBJ_DIR}/dist/bin/browser/defaults/preferences/all-gentoo.js"
-#
-#	...
-# }
