Below are some empirical definitions of what each of the "standard" Makefile targets (clean, realclean, distclean and uninstall) should do:
So in principle the complete clean-up-for-starting-over prescription is (in top CCP4 directory) to do:
> make uninstall > make distclean(You can't do it the other way around because distclean zaps the Makefiles.)
In practice there are some problems, some of which I've fixed - but the worst offender (x-windows directories) still get into a bit of a tiz. So the above prescription won't necessarily hold for the x progs (some of which seem to change the distributed files anyway). Probably not so important.
