TechnicLauncher CommandLineArguments

[Immisorator]

Main Question
I want to open a modpack (i.e. Hexxit, pixelmon, etc.) directly from steam. I still want it to auto login through TechnicLauncher and be "legal" and whatnot. I just want it to auto open the game.

Expanded Question
What are the frickin' command line arguments for TechnicLauncher.exe????? Every windows/linux program worth it's beans has it. Even minecraft, java, etc. 
But what on earth are the ones for TechnicLauncher itself.

Basically I want:

TechnicLauncher.exe -modpack "Hexxit" -fullscreen -WhateverElseMayBeRequired.

I'm on Windows, but I would like to know them for Linux as well.

Although the question isn't very politely written, Immisorator has a point.
Are there any command line arguments that can be used with the launcher?

EDIT: Don't ignore me just because I dug up a 3 years old thread ≧ ﹏ ≦
