Here is an example of an m4r script that will generate syntactically valid but randomized English sentences:
	define(`noun',`cats',`dogs',`people')
	define(`verb',`love',`hate',`ignore')
	noun verb noun
This script, when given to m4r, would yield a potentially infinite number of randomized (but syntactically valid) sentences such as cats hate dogs, people ignore cats, and so on. All of the generated sentences will have the general form noun verb noun as called for by the m4r script shown above.

The following m4r script illustrates a more practical application of the power of m4r. Here we use m4r's unique multi-definitions feature to define syntactically-valid expansions of various grammar non-terminals for a subset of the input language supported by the UNIX bc(1) bench calculator program:
	define(`digit',`0',`1',`2',`3',`4',`5',`6',`7',`8',`9')
	define(`digits',`digit',`digit`'digits')
	define(`literal',`digits')
	define(`atom',`literal',`( expression )')
	define(`primary',`atom',`primary ^ atom')
	define(`factor',`primary',`factor * atom',`factor / atom')
	define(`term',`factor',`term + factor',`term - factor')
	define(`expression',`term')
	srandom
	expression
(The direct correspondence between the m4r input shown above and the BNF syntax rules for the equivalent subset of the bc(1) input language will undoubtedly be noted by those accustomed to dealing with BNF specifications of context-free grammars.)

The m4r script shown above was used to automatically generate the following randomized but valid bc(1) input expression. This expression is quite lengthy, and is shown here wrapped onto multiple lines (for readability), but the original m4r output was actually just one very long line. It should be easy to tell from this one example that m4r can be used to automatically generate extremely challenging torture tests for any sort of program that accepts or requires syntactically complex inputs.
