+is mostly SVR4 compatible although it has some extensions (for example,
+handling more than 9 positional parameters to macros).  GNU M4 also has
+built-in functions for including files, running shell commands, doing
+arithmetic, etc.
+
+GNU M4 is a macro processor in the sense that it copies its input to the
+output expanding macros as it goes.  Macros are either builtin or
+user-defined and can take any number of arguments.  Besides just doing macro
+expansion, m4 has builtin functions for including named files, running UNIX
+commands, doing integer arithmetic, manipulating text in various ways,
+recursion etc...  m4 can be used either as a front-end to a compiler or as a
+macro processor in its own right.")
