-This is release 3.78 (September 6, 1999) of the GNU make test

-This release is made by psmith@gnu.org to correspond to GNU make 3.78.
-It won't work correctly for versions before that.  In addition to some
-infrastructure changes I've added a number of new tests.

-This package has a number of problems which preclude me from
-distributing it with make as a default "make check" test suite.  The
-most serious of these is that it's not parallelizable: it scribbles all
-over its installation directory and so can only test one make at a
-time.  I simply don't have time to do more with this than I am so far;
-I'm very actively interested in finding someone willing to overhaul the
-test suite infrastructure.  If you're interested, contact me (see below)!
-
-The test suite thus far has been written by Steve McGee, Chris Arthur,
-and Paul D. Smith.  It is covered by the GNU General Public License
-(Version 2), described in the file COPYING.
-
-The test suite requires Perl and is known to work with Perl 4.036 and
-Perl 5.004 (available from ftp.gnu.org, and portable to many machines).
-Earlier or later versions may work; I don't know.  It assumes that the
-first "diff" it finds is GNU diff, but that only matters if a test
-fails.
+The test suite was originally written by Steve McGee and Chris Arthur.
+It is covered by the GNU General Public License (Version 2), described
+in the file COPYING.  It has been maintained as part of GNU make proper
+since GNU make 3.78.
+
+The test suite has a number of problems which should be addressed.  One
+VERY serious one is that there is no real documentation.  You just have
+to see the existing tests.  Use the newer tests: many of the tests
+haven't been updated to use the latest/greatest test methods.  See the
+ChangeLog in the tests directory for pointers.
+
+The second serious problem is that it's not parallelizable: it scribbles
+all over its installation directory and so can only test one make at a
+time.  The third serious problem is that it's not relocatable: the only
+way it works when you build out of the source tree is to create
+symlinks, which doesn't work on every system and is bogus to boot.  The
+fourth serious problem is that it doesn't create its own sandbox when
+running tests, so that if a test forgets to clean up after itself that
+can impact future tests.
+
+The test suite requires Perl.  These days, you should have at least Perl
+5.004 (available from ftp.gnu.org, and portable to many machines).  It
+used to work with Perl 4.036 but official support for Perl 4.x was
+abandoned a long time ago, due to lack of testbeds, as well as interest.
+
+The test suite assumes that the first "diff" it finds on your PATH is
+GNU diff, but that only matters if a test fails.
 
 To run the test suite on a UNIX system, use "perl ./run_make_tests"
 (or just "./run_make_tests" if you have a perl on your PATH).
