1 Since metaconfig units are modular, you don't have to regenerate perl5's entire
2 Configure every time you want to test just one unit. Instead, you can
3 run metaconfig against a smaller project that tests just one (or a few)
4 units. That's what this U.check directory is for.
6 Just edit main.c and dummy.SH to use whatever metaconfig symbols you're
7 trying to test. Then run metaconfig -m to regenerate Configure.
8 You'll get a slimmed-down Configure that tests just what you want to test.
