It's a wiki.  It's publically writable.  Most of the pages on the wiki
have multiple contributors.

Haven't we already covered this?  You're using BASH_SOURCE and assuming
what will be in it conforms to a certain pattern.  And then you're calling
the script with "bash stup" which means the content of BASH_SOURCE does
*not* match the pattern you expected it to match.  It contains "stup"
rather than "./stup".

Fix your own bugs.
