Hehe, .arm. I bet there's some internet database that will tell us that ARM files are Wing Commander Armada plaintext readme documents. I do remember trying to open every individual file in the old DOS games in LED (the IBM proprietary editor)... those were the days!
Mac developers had a habit of labeling their readmes, "DON'T EVER READ THIS!" "Not worth reading" "Please don't read me" and the like. Always nice when they sneak in jokes.
Hehe... I once stumbled over a french software (it was in english or german, but made by a french company) and I searched for the readme.txt, liesmich.txt or something similar and didn't find it.
...And then I found a file named LISEZ.MOI and realized that they had forgotten to rename the readme to english. Inside I found an english readme.....
