But that's not a parallel at all, because unzip doesn't do anything
with the data that it unpacks. A better parallel might be, creating
a DVD vs. playing it back.
absurdum of the idea--but one might compile something with a dozen different
compilers and compilers might compile any one of thousands of different
and the compilers certainly don't care what the program does, and the

so their is no 'tight' link. Same with a DVD--one might burn with any
one of several
programs and play back with any one of several with no link between the
and the player, and the contents of the product--the DVD--is irrelevant
to the burner
and to the player. (So long as the standards are maintained, of course.)
OTOH zcompile produces a filespecifically and only
usable by autoload, so one might rightly think of zcompile as a subsidiary
program to autoload. I doubt you could change one without considering the
effect on the other. I'd say it's the same with zip/unzip--if one
the other must change--they are a suite of linked programs. But whereas
unzip does not 'use' the content of whatever it unzips, autoload uses
a .zwc file and is the only program that does. Thusly, a mnemonic similarity
between names would be very mildly usefulthe same way that 'unzip'
is usefully similar to 'zip'. In the real world of course, renaming
would do far more harm than good, so it's an academic discussion. Had
I been around 20 years ago, I'd have suggested naming it 'makezwc' or
something like that, or 'autoload --makezwc' or some such. One is given
a tiny but friendly hint that things are related, that's all. But unix
a friendly placeand seems not to want to be. It delights in its obscurity.
