This is the second time I've met references to fontinst v1.5; Alan very
kindly emailled me the documentation for it.  But am I puzzled: where is
it?  The most recent official version of fontinst I can find on CTAN is
1.335.  Is v1.504 an official version, and if so, where is it kept?  Or is
it being kept hidden for some particular reason?
