The wtf(6) program relies on a non-zero exit status of pkgsrc's
"make help" target, while in fact this target always returns exit
status zero, whether or not the help topic was actually found.
This makes wtf(6) display non-intended output, and exit with an
incorrect exit status. (Note: perhaps this should _actually_ be
fixed in pkgsrc?)
Also, the wtf(6) man page contains minor errors, and can use other
One ``error'' is that the man page still mentions to (solely) look
up acronyms; while in fact it still does, it nowadays looks up
terms in a more general sense, i.e., not just as acronyms in acronym
Also, the man page doesn't mention that pkgsrc's help facility is
only queried when wtf(6) is called from within a pkgsrc package
directory (or a second-level pkgsrc child directory in general);
even when this is only a side effect requirement because of wtf(6)
looking for the required mk/bsd.pkg.mk pkgsrc file to be able to
use pkgsrc's `help' make(1) target, it still is a valid requirement
on itself, with the rationale that people would only be interested
in wtf(6) displaying pkgsrc help when calling it from within pkgsrc
directories, and not in other cases.
"man -s 6 wtf"
$ cd /usr/pkgsrc/mail/mutt # or any other second-level pkgsrc child directory
$ wtf foo # choose a term wtf(6) can't find, not even by
pkgsrc's help facility
foo: No help found for foo.
$ echo $? # see the incorrect exit status from wtf(6) itself
