23 : sequence of atoms, which can be left or right parenthesis, names,
24 : integers or strings. Parenthesis are always matched which allows
25 : us to skip over sections at high speed without having to know
26 : anything about the internal structure of the lists. A "name" is
27 : usually a fortran 95 identifier, but can also start with '@' in
28 : order to reference a hidden symbol.
29 :
30 : The first line of a module is an informational message about what
31 : created the module, the file it came from and when it was created.
32 : The second line is a warning for people not to edit the module.
33 : The rest of the module looks like:
34 :
35 : ( ( <Interface info for UPLUS> )
36 : ( <Interface info for UMINUS> )
37 : ...
38 : )

41 : )
42 : ( ( <name of generic interface> <module of generic interface> <i/f1> ... )

45 : ( ( <common name> <symbol> <saved flag>)
