  this email didn't reach the list, so I'm resending it -
  hopefully nobody will get it twice ... ]

There's a small bug in gsftopk causing `gsftopk --debug=x' to
always display the `Usage' string; e.g.:

$ gsftopk --debug 8 --test cmr10
Usage:  gsftopk [OPTION] FONT DPI
Translate the PostScript Type 1 font FONT to PK bitmap format at DPI dpi.

  -t, --test            check for presence of font in .map file.
  --mapline=LINE        use LINE as the line from the .map file.
  --mapfile=FILE        use FILE as a .map file; default psfonts.map.
  -i GS, --interpreter=GS  use GS as Ghostscript interpreter.
  --dosnames            short pk filename (cmr10.pk instead of cmr10.600pk).
  -q, --quiet           don't print progress information to standard output.
  --debug=NUM           set debugging flags.
  -h, --help            print this message and exit.
  -v, --version         print version number and exit.

The reason is a missing `break' statement in gsftopk.c:

(version is gsftopk(k) 1.19 from the current teTeX-beta-20011103).

Another observation: By default, gsftopk uses kpathsearch to
search for the map-file; however, when the `--mapfile' option is
used, kpathsearch is *not* used:

$ gsftopk ptmr8r 600
[ normal output of PK generation ]
$ gsftopk --mapfile=psfonts.map ptmr8r 600
psfonts.map: No such file or directory
$ kpsewhich psfonts.map
$ gsftopk --mapfile=/usr/share/texmf/dvips/base/psfonts.map ptmr8r 600
[ normal output of PK generation ]

This is documented in gsftopk.1, but wouldn't it be more consistent
to use kpathsearch in both cases? E.g.:
