I had initially assumed that scripts belonged in the "scripts"
directory.  That didn't work.  Then I tried the top of the source
directory.  That didn't work either.  I finally figured out that the
script path wasn't interpreted relative to a fixed point, but it was
left up to the shell to find using the normal PATH mechanism (so it
had to be ./filename rather than filename).

I'll submit a patch to the docs.

I will.
