 # Only a fool would alias REM to # so that REM lines will work on unix. Luckily, I am a fool.
 # Please note that this is case-sensitive. I have not aliased all the case variants; out of personal taste (I always write my REM lines with REM in caps, for visual distinctness), and also so that (*checks notes*) the rem command of the remind package will not conflict with this. This alias also does not end in a space, so the command after it will not be alias-expanded. This particular omission is on purpose (in the rest of the file the omissions were not carefully considered), because REM is supposed to be a comment so the less that is done in there the better.
