>Notes:
>
>* The list of aliases is sorted by alias, the list of 
>  literal globs is sorted by the literal. The SuffixTreeNode
>  siblings are sorted by character. The list of namespaces
>  is sorted by namespace uri.
>
>* All offsets are in bytes from he beginning of the file
>
>* Strings are zero-terminated
>
>* All numbers are in network (big-endian) order. This is
>  necessary because the data will be stored in arch-independent
>  directories like /usr/share/mime or even in user's 
>  home directories.
>
>* Cache files have to be written atomically - write to a
>  temporary name, then move over the old file - so that
>  clients that have the old cache file open and mmap'ed
>  won't get corrupt data.
