+# 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
