Added at least some explanation of all this stuff.

	* tests/README: Added at least some explanation of all this stuff.

	* tests/lib/camel-test.h (check_msg): Added a non-gcc version of
	the fail command, we dont get the expression that failed, but no
	matter.  Should be (more) portable now.
	(check, check_msg): Put the file/lineno in the default message.

+
+This directory is to contain regression tests that should be run
+before committing anything to camel.
+
+To write a new test: copy an existing one and replace the contents.
+
+See camel-test.h for a number of functions and macros which setup and
+define the test environmet, and help provide meaningful messages when
+something actually fails.
+
+All tests have the following options:
+ -v[vvvv]
+	verbose.  more v's more verbose.  2 v's will give you
+	a simple test backtrace of any partially failed tests.
+	No v's give you a simple backtrace of any failed tests.
+ -q
+	quiet.  Dont print anything, unless there is a SEGV.
+
+See the other files in lib/* for utility functions that help to
+write the tests (object comparison, creation, etc functions).
+
+Tests may fail and be non-fatal.  In this case, you will see "Partial
+success" on the result of each test line.  To get more information
+about the test, run the test manually with a -v command line argument.
+The more v's you have the more detail you get (upto about -vvvvv),
+generally use -vv to find out which parts of a partially successful
+test failed, and where.
+
+Note that if writing tests, non-fatal tests (bracketed by a
+camel_test_nonfatal() and camel_test_fatal() pair) should only be
+defined where: 1. The test in question should ideally pass, and 2. The
+code has known limitations currently that stop it passing, but
+otherwise works for nominal input.
+
+To debug tests, set a breakpoint on camel_test_fail, which will be
+called for any failure, even a non-fatal one.
