One can't be sure that the COPYING + file is in .. or ../.. in all situations, the ../Makefile is + always there. + + * doc/m4.texinfo (Include): adjusted expected test output + according to new tests, i.e. the input will always come from the + file `in' created by the test. + + * tests/Makefile.am: Added three lines at the top to get + esyscmd.1.test working. + + * tests/get-them: modified to generate clearer tests who will need + less maintenance when new test examples are created in + `doc/m4.texinfo'. All tests are small (nearly stand-alone, they + need the generic file `defs') shell scripts creating `in', `ok', + `out' and when apropriate `okerr' and `err' in the directory + `testSubDir' when executed. The compare of `ok' and `out' + (and of `okerr' and `err') will be the exit status of the test. + `out' must match `ok' (and `okerr' must match `err') for the test + to be succesful. + + * tests/[a-b]\{1,8\}.[0-9]+.test: This namespace is reserved for + the tests generated by tests/get-them getting it input normally + from doc/m4.texinfo. The namespace tests/[a-b]+[0-9]+.test (no `.' + (dot) before the numeric part) is reserved for all other (hand + written) tests.
