+ At least for now, we only support archives with the same byte
+ ordering in the armap and the contents.
+
+ The first four bytes in the armap are the number of symbol

+

+ this symbol. The second four bytes are the file offset to the
+ archive member which defines this symbol. If the second four bytes
+ are 0, then this is not actually a symbol definition, and it should
+ be ignored.
+
+ The symbols are hashed into the armap with a closed hashing scheme.
+ See the functions below for the details of the algorithm.
