(synopsis "Macro processor")
(description
- "GNU M4 is an implementation of the traditional Unix macro processor. It
-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.")
