This is the main test suite for AnaGram.

	bugs		Current tests written to exercise bugs.
	contrib		Test material contributed from elsewhere.
	eval-[ep]	A copy of evalExpression. (That needs attention.)
	examples	Test by building the examples.
	ffcalc		A gazillion variants of ffcalc.
	oldagsrc	Tests based on old versions of AG source and examples.
	parsifal	Other tests from the Parsifal Software era.
	silly		Simple and absurd tests.

Note that we do not recommend looking in here for example code. Use
the examples for that! A lot of what's in here is here because it
broke AG at one time or another, and often that's because it had bugs
and was therefore doing something crazy. A lot of the tests are
weirdly mangled, sometimes in subtle ways, and don't make good
material to learn from or crib from.
