+# match -- compare an output file with expected results
+#
+# usage: match [-adoqv] [match-file]...
+#
+# this script compares the output from a test run, stored in a file, with
+# the expected output.  comparison is done line-by-line until either all
+# lines compare correctly (exit code 0) or a miscompare is found (exit
+# code nonzero).
+#
+# expected output is stored in a ".match" file, which contains a copy of
+# the expected output with embedded tokens for things that should not be
+# exact matches.  the supported tokens are:
+#
+#	$(N)	an integer (i.e. one or more decimal digits)
+#	$(NC)	one or more decimal digits with comma separators
+#	$(FP)	a floating point number
+#	$(S)	ascii string
+#	$(X)	hex number
+#	$(XX)	hex number prefixed with 0x
+#	$(W)	whitespace
+#	$(nW)	non-whitespace
+#	$(*)	any string
+#	$(DD)	output of a "dd" run
+#	$(OPT)	line is optional (may be missing, matched if found)
+#	$(OPX)	ends a contiguous list of $(OPT)...$(OPX) lines, at least
+#		one of which must match
+#
+# Additionally, if any "X.ignore" file exists, strings or phrases found per
+# line in the file will be ignored if found as a substring in the
+# corresponding output file (making it easy to skip entire output lines).
+#
+# arguments are:
+#
+#	-a	find all files of the form "X.match" in the current
+#		directory and match them again the corresponding file "X".
+#
+#	-o	custom output filename - only one match file can be given
+#
+#	-d	debug -- show lots of debug output
+#
+#	-q	don't print log files on mismatch
+#
+#	-v	verbose -- show every line as it is being matched
+#
