+
+Here are some notes about adding and using this testsuite.
+
+First, all the programs are linked with new-libcygwin.a, which is just
+like libcygwin.a, except that it wants new-cygwin1.dll, not
+cygwin1.dll.  The testsuite adds the winsup build directory to the
+PATH so that new-cygwin1.dll can be found by windows during testing.
+
+Because we'll probably run into complaints about using two DLLs, we
+run cygrun.exe for each test.  All this does is run the test with
+CreateProcess() so that we don't attempt to do the special code for
+when a cygwin program calls another cygwin program, as this might be a
+"multiple cygwins" problem.
+
+Any test that needs to test command line args or redirection needs to
+run such a child program itself, as the testsuite will not do any
+arguments or redirection for it.  Same for fork, signals, etc.
+
+The testsuite/winsup.api subdirectory is for testing the API to
+cygwin1.dll ONLY.  Create other subdirs under testsuite/ for other
+classes of testing.
+
+Tests in winsup.api/*.c or winsup.api/*/*.c (only one subdirectory
+level is allowed) either compile, run, and exit(0) or they fail.
+Either abort or exit with a non-zero code to indicate failure.  Don't
+print anything to the screen if you can avoid it (except for failure
+reasons, of course).  One .c file per test, no compile options are
+allowed (we're testing the api, not the compiler).
+
+Tests whose filename begin with "xf-" will be *expected* to fail, and
+will "fail" if they compile, run, and return zero.  Note that the
+*only* purpose for adding this feature is to test the testing
+framework itself.  All real tests should NOT be named xf-*, and should
+pass for real (compile, run, return 0) if the dll is working
+correctly.  Do not use xf-* to "silence" a failure that you know isn't
+going to get fixed for a while; let it just keep failing.  There are
+five "sample" tests that demonstrate how the framework works and what
+happens to each condition.
+
+"make check" will only work if you run it *on* an NT machine.
+Cross-checking is not supported.
