oh. i thought brandelf's purpose was to adjust an executable's OS ABI on a
general basis. an example would be having solaris executables with the OS ABI
set to 0. although freebsd won't support running these binaries brandelf could
be used to correct the OS ABI value which might come in handy if you're using
freebsd for backup purposes e.g.
or is this purpose covered by a different application in the base dir?
cheers.
