2016-03-02 Simon J. Gerraty <sjg@bad.crufty.net>
* meta2deps.sh: don't ignore subdirs.
patch from Bryan Drewery
2016-02-26 Simon J. Gerraty <sjg@bad.crufty.net>
* install-mk (MK_VERSION): 20160226
* gendirdeps.mk: mark _DEPENDFILE .NOMETA
2016-02-20 Simon J. Gerraty <sjg@bad.crufty.net>
* dirdeps.mk: we shouldn't normally include .depend but if we do
use .dinclude if we can.
2016-02-18 Simon J. Gerraty <sjg@bad.crufty.net>
* install-mk (MK_VERSION): 20160218
* sys.clean-env.mk: with recent change to Var_Subst()
we cannot use the '$$' trick, but .export-literal does the job
we need.
* auto.dep.mk: make use .dinclude if we can.
2016-02-05 Simon J. Gerraty <sjg@bad.crufty.net>
* dirdeps.mk:
Add _build_all_dirs such that local.dirdeps.mk can
add fully qualified dirs to it.
These will be built normally but the current
DEP_RELDIR will not depend on then (to avoid cycles).
This makes it easy to hook things like unit-tests into build.
2016-01-21 Simon J. Gerraty <sjg@bad.crufty.net>
* dirdeps.mk: add bootstrap-empty
2015-12-12 Simon J. Gerraty <sjg@bad.crufty.net>
* install-mk (MK_VERSION): 20151212
