Attached is a patch for a magic addition to support AppleDouble and
AppleSingle, Apple binary disk formats, by way of Larry C. Stone
<lcs@mit.edu>.
It occurs to me belatedly that there may be some other custom Apple
file formats that may be found useful to file, and that there may be
magic information on them from the A/UX (Apple's Unix for Macintosh)
distribution. I've thusly attached the magic file from A/UX 2.01.
I note that the AppleDouble magic entry from it is slightly less-specific
than Larry's but I don't really know what to conclude, nor do I have
the specification for the file-format available to me (or at least,
not to my knowledge).
I admit to lameness in failing to extract the redundant or useful
magic entries from the A/UX magic file, perhaps if the file
maintainers have spare time? :-)
Larry is also correct that the Magdir/Header text is a little
inaccurate. I corrected it for our local installation but not
in a generic fashion...
Also at the end are some patches that jhawk@bbnplanet.com (hat switch)
had been batching to send to you the next time I sent updates.
I see that file 3.23 came out. These patches are against 3.22, but there
don't seem to be any real conflicts. jhawk@bbnplanet.com had submitted to you
some stuff on 22 July that seems completely missing in 3.23. I'll resend that
to you on the assumption it got dropped, as I think the additions were sane.

The file command doesn't know about AppleSingle and AppleDouble files,
which are an exchange file format and thus likely to show up on Unix.
These always contain binary data, although they may also have a text
data fork. Here are two lines to add to the appropriate magic subfile:
0 long 0x00051600 AppleSingle encoded Macintosh file
0 long 0x00051607 AppleDouble encoded Macintosh file
Also, I notice the header in share/magic says to edit the source files
in a non-existent directory, which should be updated to src/file-3.22/Magdir.
