- * Switches are;
- * -[v,Q] verbose or not quiet: prints out type
- * and routine information as mig runs.
- * -[V,q] not verbose or quiet : don't print
- * information during compilation
- * (this is the default)
- * -[r,R] do or don't use rpc calls instead of
- * send/receive pairs. Default is -r.
- * -[s,S] generate symbol table or not: generate a
- * table of rpc-name, number, routine triplets
- * as an external data structure -- main use is
- * for protection system's specification of rights
- * and for protection dispatch code. Default is -s.
- * -i <prefix>
- * Put each user routine in its own file. The
- * file is named <prefix><routine-name>.c.
- * -user <name>
- * Name the user-side file <name>
- * -server <name>
- * Name the server-side file <name>
- * -header <name>
- * Name the user-side header file <name>
- * -iheader <name>
- * Name the user-side internal header file <name>
- * -sheader <name>
- * NAme the server-side header file <name>
- *
- * 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.
