-Usage: %prog [options] [master-file]
-
-This script filters a list of exports from a DLL, generated from something
-like the following command line:
-
-C:\> dumpbin /exports user32.dll
-
-against a master list of imports built from e.g.
-
-C:\> dumpbin /exports user32.lib
-
-The point of this is to trim non-public exports from the list, and to
-normalize the names to their stdcall-mangled form for the generation of
-import libraries.
-Note that the export names from the latter incanatation are stdcall-mangled,
-e.g. they are suffixed with "@" and the number of argument bytes to the
-function.
