# Manifest construction.  There are 5 sources for manifests we need to collect
# in $(MPROTO) before running the manifest tool.  One each comes from
# illumos, illumos-extra, and the root of live (covering mainly what's in src).
# Additional manifests come from each of $(LOCAL_SUBDIRS), which may choose
# to construct them programmatically, and $(OVERLAYS), which must be static.
# These all end up in $(MPROTO), where we tell tools/build_manifest to look;
# it will pick up every file in that directory and treat it as a manifest.
#
# In addition, a separate manifest is generated in similar manner for the
# boot tarball.
#
# Look ma, no for loops in these shell fragments!
