| 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). `m4' also has builtin functions for including files, |
| running shell commands, doing arithmetic, etc. Autoconf needs GNU |
| `m4' for generating `configure' scripts, but not for running them. |
| |
| GNU `m4' was originally written by Rene' Seindal, from Denmark. |
| |
| GNU `m4' has a web site at http://www.gnu.org/software/m4/. |

| This repository has several branches. The one you have checked out |
| does not have any code. Instead, you will want to check out one of: |
| - branch-1.4: Latest stable release, most up-to-date |
| - branch-1.6: Some improvements to 1.4, but not yet finalized and released |
| - branch-2.0: Many new experimental features, hasn't been worked on in years |

| For any copyright year range specified as YYYY-ZZZZ in this package |
