# The prefab brain file is not especially portable (see the top of
# brain.c in knightcap; the file is a binary array of brain_entry) and
# while most of it is adequate but not ideal and should be portable
# among platforms of the same endianness (even ILP32 vs. LP64 ones),
# it unfortunately contains two fields of type time_t. We think the
# posted brain file is from 32-bit x86, probably Linux, so it will
# work on little-endian machines where time_t is still 32 bit. This
# excludes at least NetBSD 6.0 and up, and at least some of the 64-bit
# Linux ports, but I don't know for sure which ones. So begin by
# allowing little-endian platforms and then excluding ones known not
# to work. Add more as needed; a brain file with mismatched time_t
# won't load. Note that while the existing brain file could easily be
# translated, if anyone feels like doing that they should probably
# translate the posted one to a portable format (e.g. compressed JSON
# or something, or just plain text) and provide a loader for that
# format upstream.
