|
|
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.
