Yes, GNAT project files are understandable, though non-portable TTBOMK.
(I find its idiolect a little inconsistent WRT to plurals and lists.)

Gpr files will likely not be used by those who code for Intel's
Fortran compiler, or the C part of GCC; they can easily specify
IFCOPTS or GCCOPTS referenced in Makefiles.

The Makefile for all C programs, or C++ programs, and a number of other
languages currently looks simlar to this:

%.c : %.systematic-name
	mv $< $@

%.executable : %.c
	$(CC) -pipe -Wall $(COPTS) $(GCCOPTS) $< -o $@

So the source text can be all in one file, the translation is kept simple.
GNAT also gets only two lines, one for gnatchop, the other for gnatmake.
