[clug] Micrografx ABC SnapGraphix file

[Bryan Kilgallin]

I am reviewing twenty-three year old "SG" files. I recall that they 
would have been corporate diagrams. The files are small (six to 52 kB). 
Ubuntu Files (Nautilus) says they are "Sega Master System/Game Gear ROM 
(application/x-sms-rom)"!

{The sg file extension is related to an old program called Micrografx 
ABC SnapGraphix and used for files that contains saved user settings.

The Micrografx, Inc. was acquired by Corel corp. in 2001 and Micrografx 
software portfolio was integrated to the Corel's applications.

This sg file type entry was marked as obsolete and no longer supported 
file format.}

{Micrografx ABC SnapGraphix was application used to create graphics 
flows and organisation charts. Micrografx was acquired by Corel.}

I have been unable to open the files looking other than gibberish!
