15             Welcome to the Eriantys startup tool!
16                                 
17             This tool must be called with at least one of the following arguments:
18                 < s > will start the Server (default bound to 0.0.0.0:8080) [ max instances: 1 ]
19                 < g > will start a GUI [ max instances: unlimited ]
20                 < c > will start the CLI [ max instances: 1 ]
21                 < h > or < -h > will print this message [ max instances: 1 ]
22                                 
23             Additionally, one or more of the following arguments may be used:
24                 < -d > will enable the logger, useful for debugging [ max instances: 1 ]
25                 < -local > will force the server to bind to the loopback address of the machine [ max instances: 1 ]
26                 < -port: > followed (without using spaces) by the port the server will be listening to [ max instances: 1 ]
27                              
28             Here are some examples of argument combinations:
29                 -d -local -port80 s         [starts the server binding it to 127.0.0.1:80 and enables the logger]
30                 -port:420 s                 [starts the server binding it to 0.0.0.0:420]
31                 -d g                        [starts the GUI enabling the logger]
32                 c                           [starts the CLI]
33                 -local s g g c              [starts a local server (127.0.0.1:8080) along side 2 GUIs and 1 CLI]
