# The following entries for the Apple II are for files that have
# been transferred as raw binary data from an Apple, without having
# been encapsulated by any of the above archivers.
#
# In general, Apple II formats are hard to identify because Apple DOS
# and especially Apple ProDOS have strong typing in the file system and
# therefore programmers never felt much need to include type information
# in the files themselves.

# AppleWorks word processor:
#
# This matches the standard tab stops for an AppleWorks file, but if
# a file has a tab stop set in the first four columns this will fail.
#
# The "O" is really the magic number, but that's so common that it's
# necessary to check the tab stops that follow it to avoid false positives.

# AppleWorks database:
#
# This isn't really a magic number, but it's the closest thing to one
# that I could find.  The 1 and 2 really mean "order in which you defined
# categories" and "left to right, top to bottom," respectively; the D and R
# mean that the cursor should move either down or right when you press Return.

# AppleWorks spreadsheet:
#
# Likewise, this isn't really meant as a magic number.  The R or C means
# row- or column-order recalculation; the A or M means automatic or manual
# recalculation.

# Some attempts at images.
#
# These are actually just bit-for-bit dumps of the frame buffer, so
# there's really no reasonably way to distinguish them except for their
# address (if preserved) -- 8192 or 16384 -- and their length -- 8192
# or, occasionally, 8184.
#
# Nevertheless this will manage to catch a lot of images that happen
# to have a solid-colored line at the bottom of the screen.
