39 * This client was substantially modified and enhanced by Elliot Poger
40 * for use on Linux while he was working on the MosquitoNet project at
41 * Stanford.
42 *
43 * The current version owes much to Elliot's Linux enhancements, but
44 * was substantially reorganized and partially rewritten by Ted Lemon
45 * so as to use the same networking framework that the Internet Software
46 * Consortium DHCP server uses. Much system-specific configuration code
47 * was moved into a shell script so that as support for more operating
48 * systems is added, it will not be necessary to port and maintain
49 * system-specific configuration code to these operating systems - instead,
50 * the shell script can invoke the native tools to accomplish the same
51 * purpose.
