The alt code lets one redefine the port and also redefine the timing constants. The reason for the port is in case of firewall (though on localhost that shouldn't be a problem but it does appear to be that it might bind to other addresses too). The timing one the author specifies some uses for changing it. Uses #ifndef..#endif. Format/typo check README.md file.
