gen_cvs_header
==============
Print some fancy header like those of CVS, like OpenBSD's for pasting into your files.
Uses only the standard library.

Build
-----
Requires the Go toolchain, the go.mod file says 1.19 but anything earlier will work I think, like 1.14 or something.

Usage
-----
Pass the following environment variables to it with `env` or you can also export them into your shell

* CVS_AUTHOR
* CVS_FILE
* CVS_ID
* CVS_VERSION
