/*
 * generator.c -- phase 2 of the generator.
 *
 * takes a file, which has a list of signature as input,
 * and outputs the client, server, .xg, and makefiles
 * This file is normally created by running tableGen.c,
 * but theoretically could be generated by a human.
 *
 * Format of the signatures : no_of_args list_of_arg_signs
 *  arg_sign : (dir type)
 *
 *
 * This program is used to generate client/server pairs that
 * make and verify random rpcs.  It can be used to generate
 * both pthread and lwp versions of the client and server.
 * It was designed to verify that the new pthread rx library
 * was functioning correctly.
 *
 * The key to understanding how this program works is to realize
 * that all the data necessary to generate the client/server
 * code is generated first, in char string format.
 * For example, if you are generating 10 rpc's, the input and
 * output values of all the parameters are generated - and
 * stored as strings.  This allows you to write out the values
 * as the client and server are created without having to worry
 * about data type conversion.
 *
 * In addition, these strings (along with other information) are
 * stored in a structure that is iterated over many times during
 * the construction of the client and server.
 *
 * Often this iteration takes the form of:
 *     for (i=0; i < argsP->argCount; i++)
 *
 * It may be possible to eliminate some of these iterations for
 * efficiency sake, but this was not done - allowing an easier
 * implementation.
 *
 * The bulk of this code was lifted from the delight project.
