Comment #5 on issue 2158 by address@hidden: Patch: Sketch of not  
remaking html files

Should probably have associated this with  
http://code.google.com/p/lilypond/issues/detail?id=2028.  It's an attempt  
to stop make doc recreating the whole of build/out-www/offline-root/ every  
time it's run, whether any of the files there have been change or not.  It  
changes the make file to stop it blindly deleting that directory, and then  
www_post.py to allow for the fact that the directory/ies might exist.  It  
then checks whether the target file is newer than the source before  
recreating the target.  On my quick machine, make LANGS='' doc where there  
is no work to do now only takes 5 seconds, as opposed to nearly 20.  On my  
slow VM, it reduces the time from 2m 30s to 40s.  I've tested it with a  
fresh make doc and confirmed all the required files exist after the make.
