# BEGIN SpiderMonkey header installation
#
# Mozilla/Gecko/Firefox mostly doesn't concern itself with defining a sensible
# install target, because it's shipping primarily packaged builds.  And even if
# it did, those builds wouldn't really have reason to include header files.  So
# we have to install public headers ourselves, rather than using something from
# config/rules.mk or similar.
#
# The overall directory structure of the installed headers looks like so:
#
#   $(includedir)/
#      $(LIBRARY_NAME)/
#        jsapi.h, jspubtd.h, etc. (all of EXPORTS)
#        js/
#          js/public/* headers (all are public)
#        ds/
#          js/src/ds/* public headers
#        gc/
#          js/src/gc/* public headers
#        mozilla/
#          mfbt headers
