# kerberos: MIT kerberos file binary formats
#
# This magic entry is for demonstration purposes and could be improved
# if the following features were implemented in file:
#
# Strings inside [[ .. ]] in the descriptions have special meanings and
# are not printed.
#
# - Provide some form of iteration in number of components
# [[${counter}=%d]] in the description
# then append
# [${counter}--] in the offset of the entries
# - Provide a way to round the next offset
# Add [R:4] after the offset?
# - Provide a way to have optional entries
# XXX: Syntax:
# - Provide a way to "save" entries to print them later.
# if the description is [[${name}=%s]], then nothing is
# printed and a subsequent entry in the same magic file
# can refer to ${name}
# - Provide a way to format strings as hex values
