    I'm looking for documentation [formal or informal] on the specifics of
    the file format that is commonly referred to JPEG or JPG [i.e.,
    FILENAME.JPG or FILENAME.JPEG] ... you know, for the *.JPG files that
    show up in the alt.binaries.pictures.* groups.

    I assume that this isn't just a naming convention [the use of the
    .JPG/.JPEG extension] to mark TIFF V6.0 files which use the JPEG/DCT
    compression extensions.

    Information by reference or by value (i.e., pointers or e-mailed
    copies) would be appreciated.  (I'm not interested in pointers to
    existing conversion programs; and I'm only slightly interested in code
    that reads and writes these files.  I'd really prefer something akin to
    a format spec.)

    Also I'd appreciate knowing the relationship between the data commonly
    stored in these files and the revision level of the JPEG spec.

    If anyone can help, I'd prefer e-mail, but I don't mind posted
    followups (it's just that I don't keep up with this newsgroup).

    Thanks in advance.
