# This Makefile is used to kick off a static rooting analysis. This Makefile is
# NOT intended for use as part of the standard Mozilla build. Instead, this
# Makefile will use $PATH to subvert compiler invocations to add in the sixgill
# plugin, and then do a regular build of whatever portion of the tree you are
# analyzing. The plugins will dump out several xdb database files. Various
# analysis scripts, written in JS, will run over those database files to
# produce the final analysis output.
