+ How does this releate to the rest of GAS ?
+
+ Well, all the other files in gas are more or less a black box. It
+ takes care of openning files, parsing command lines, stripping blanks
+ etc etc. This module gets a chance to register what it wants to do by
+ saying that it is interested in various pseduo ops. The other big
+ change is write_object_file. This runs through all the data
+ structures that gas builds, and outputs the file in the format of our
+ choice.
