+## Cleanup the vendor tree. The main issue here is that civi Civi is
+## deployed as a module inside a CMS, so all its source-code gets published.
+## Some libraries distribute admin tools and sample files which should not
+## be published.
+##
+## This script should be idempotent -- if you rerun it several times, it
+## should always produce the same post-condition.
