Micrognosis Compression Archiver

Micrognosis Compression Archiver, sometimes called MAR, is a compressed archive utility for DOS (and maybe other platforms?).

The software is a bit vague about who exactly is responsible for it. No doubt Haruhiko Okumura had a lot to do with it, but it would be nice to have independent confirmation of a connection between him and Micrognosis. The credits for version 1.0 say: Original Version By:          Stratus VOS 11.5 Version by: Haruhiko Okumura             Richard Schiller

Format details
MAR uses generalized LHA format, with some custom compression schemes:

It also uses the standard " " scheme, for uncompressed files.

The documentation lists more compression schemes, but they don't seem to be implemented:

Identifiers
The executable file is named "MAR.EXE". MAR does not seem to have a standard filename extension, though one might logically use .MAR.
