LibCSS testcases=============== Testcases for LibCSS are self-contained binaries which test various partsof the CSS library. These may make use of external data files to drivethe testing. Testcase command lines---------------------- Testcase command lines are in a unified format, thus:  	<aliases_file> [ <data_file> ] The aliases file parameter will always be specified (as it is required forthe library to work at all). The data file parameter is optional and may be provided on a test-by-testbasis. Testcase output--------------- Testcases may output anything at all to stdout. The final line of theoutput must begin with either PASS or FAIL (case sensitive), indicatingthe success status of the test. Test Index---------- In the test sources directory, is a file, named INDEX, which provides anindex of all available test binaries. Any new test applications should beadded to this index as they are created. The test index file format is as follows: 	file         = *line 	line         = ( entry / comment / blank ) LF 	entry        = testname 1*HTAB description [ 1*HTAB datadir ]	comment      = "#" *non-newline	blank        = 0<OCTET> 	testname     = 1*non-reserved	description  = 1*non-reserved	datadir      = 1*non-reserved 	non-newline  = VCHAR / WSP	non-reserved = VCHAR / SP Each entry contains a mandatory binary name and description followed byan optional data directory specifier. The data directory specifier isused to state the name of the directory containing data files for thetest name. This directory will be searched for within the "data"directory in the source tree. If a data directory is specified, the test binary will be invoked foreach data file listed within the data directory INDEX, passing thefilename as the second parameter (<data_file>, above). Data Index---------- Each test data directory contains a file, named INDEX, which provides anindex of all available test data files. The data index file format is as follows: 	file         = *line 	line         = ( entry / comment / blank ) LF 	entry        = dataname 1*HTAB description	comment      = "#" *non-newline	blank        = 0<OCTET> 	dataname     = 1*non-reserved	description  = 1*non-reserved 	non-newline  = VCHAR / WSP	non-reserved = VCHAR / SP Each entry contains a mandatory data file name and description.
