Otherwise, the shortName is used. + + The base name (let's call it 'base') will then be used to + create the C macros SN_base, LN_base, NID_base and OBJ_base. + + Note that if the base name contains spaces, dashes or periods, + those will be converte to underscore. + +Then there are some extra commands: + + !Alias foo 1 2 3 4 + + This just makes a name foo for an OID. The C macro + OBJ_foo will be created as a result. + + !Cname foo + + This makes sure that the name foo will be used as base name + in C. + + !module foo + 1 2 3 4 : shortName : Long Name + !global + + The !module command was meant to define a kind of modularity. + What it does is to make sure the module name is prepended + to the base name. !global turns this off. This construction + is not recursive. + +Lines starting with # are treated as comments, as well as any line starting +with ! and not matching the commands above. + |
