I find the man pages descriptions of both true and false zen like and have wanted to make t-shirts out of them for years. On Ubuntu, the man page copyright is claimed by FSF, can I make a shirt?
Is it under GPL, or under GFDL? If the latter, you probably have to include a rant by Richard Stallman about the magic of Free Software on the back of the shirt (GFDL has clauses to force you to reproduce… well, that).
Only if you provide the source code for the shirt upon request
It's provided on the shirt itself (self-evident), so it should be fine to distribute copies of the shirt.
The GPL also requires providing a copy of the license.
Put it on the back of the shirt.
You could include it on the care instructions tag in tiny tiny print.
Problematic if you wear the shirt in public and allow someone to take your picture. You must provide them a copy too or your license to wear the shirt is revoked.
> ... your license to wear the shirt is revoked.
Well, you have 30 days time to comply.
No no, the source code for the shirt. You know, the code you compiled into fabric and stitching.
