Thanks a lot for the explanation, Bruno.

As Debian does not have any designated directory in the PATH for shell
script function libraries, it clearly follows that /usr/bin is the
only sensible directory where gettext.sh may be placed.

I'm glad that Debian policy does not say that /usr/bin must not contain
non-executables, because that would be a bug in policy :-)

Closing this report (which is not really a bug).
