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.

Noteworthy changes in release 1.4.18b (2021-05-07) [beta]

* The symbol hash table now defaults to 65537 buckets instead of 509, as
   modern systems have enough memory to benefit from fewer hash collisions
   by default.

* Introduce the use of gettext, with the immediate benefit of nicer
   UTF-8 author names.  Over time, more translations of program messages
   will become available.
