If there is not a lot of extra memory / time overhead associated with
this, I could see this being a valid approach. I would request that,
if implemented, this be placed behind an on/off switch.
The makefile could also handle this with something along these lines
(correct the leading space -> tab conversion as well as proper macro
definitions):
tangleflag: totangle.org
$(TANGLECOMMAND) totangle.org
$(TOUCH) tangleflag
syncflag: tangleflag
$(SYNCCOMMAND) sourcedir tangledir
$(TOUCH) syncflag
