-objects.txt syntax
-------------------
-
-To cover all the naming hacks that were previously in objects.h needed some
-kind of hacks in objects.txt.
-
-The basic syntax for adding an object is as follows:
-
-        1 2 3 4         : shortName     : Long Name
-
-                If the long name doesn't contain spaces, or no short name
-                exists, the long name is used as basis for the base name
-                in C.  Otherwise, the short name 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 juts 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.
