The GS port of djpeg version 6 uses GIF as the default output format.
I figured most people would want a GIF file, as most viewers seem to 
support GIF.  Usually, Unix versions of djpeg do use PPM as the default.

No, djpeg is not smart enough to decode the extension on the output
file.  You have to use the switches if you want anything other than
GIF.

[and from another post]

I checked the files, and they both say that -maxmem takes it's argument
in kb.  You can also use -maxmem xm, where x is now in millions of bytes.
The man page did, however, still say that PPM was the default output
format, which is wrong.  I use the ORCA shell, so I didn't check the man
pages too carefully :)
