Hello!
In the GNU MIG package, I'd like to move the `migcom' program out of
`[exec_prefix]/libexec/' (which is where is currently is being installed)
and install it alongside the `mig' program into `[exec_prefix]/bin/' for
being able to use it directly, avoiding constructs like ``$(MIG) -cc cat
- /dev/null'' as a replacement for directly calling `migcom'.
This means that `migcom' should support the basics of the GNU coding
standards, i.e. some `--version' and `--help' output. Ben, are you
interested in quickly implementig that? Or is someone else?
Regards,
Thomas
If that's ok, i can add/modify whatever else is needed.

* DESIGN:
* Mig uses a lexxer module created by lex from lexxer.l and
* a parser module created by yacc from parser.y to parse an
* interface definitions module for a mach server.
* The parser module calls routines in statement.c
* and routines.c to build a list of statement structures.
* The most interesting statements are the routine definitions
* which contain information about the name, type, characteristics
* of the routine, an argument list containing information for
* each argument type, and a list of special arguments. The
* argument type structures are build by routines in type.c
* Once parsing is completed, the three code generation modules:
* header.c user.c and server.c are called sequentially. These
* do some code generation directly and also call the routines
* in utils.c for common (parameterized) code generation.
