-2) Make a top level directory someplace, to play in, and copy trpm into
that directory.

-1) Make sure that you have sudo access.

0) Mount a pile of rpms somewhere. I conventionally use /X.Y/RPMS, where
X.Y candidates are (Red Hat) 5.2 6.2 7.0 7.1 ...

1) Eyeball the package glob expression precursors that look like
	min0glob="
	basesystem-
	bash-[12]
	filesystem-
	glibc-common-
	glibc-2
	ldconfig-
	libtermcap-2
	mktemp-
	setup-
	termcap-
	"
These are handcrafted to Do The Right Thing when presented with 5.2/6.2/7.0/...
package piles. Feel free to change to whatever, 'tain't hard.

2) Generate package manifests and rpm configuration, something like
	./trpm 7.2 config manifest
Examine the generated package manifests, they look like foo-X.Y-arch.
Ditto rpm configuration, rpmrc-X.Y. Feel free to change to whatever,
'tain't hard.

3) Install in a local ./X.Y chroot
	./trpm 7.2 min0 --initdb -Uvv

4) Test the chroot install
	./trpm 7.2 min0 chroot

5) Try a bigger test:
	sudo rm -rf 7.2
	./trpm 7.2 build --initdb -Uvv
	./trpm 7.2 chroot
	(you should be able to compile and debug a C program here)

6) Diddle the toy trpm script to taste and be happy.
