git - How to install Github for Windows offline? -

as question says how install github windows without internet connection? if not possible there alternative client following features:

• support proxy
• offline installer

i found smartgit has offline installer seems doesn't have proxy support.

if there no such client can done extend functionality of github windows or other client? mean there way use api extend it? links helpful.

"github windows" 1 of magical/annoying clickonce apps. ideal apps tend require online operate (like posting online source control website...)

other magic "clone windows" feature website, , self contained ssh auto-management (also semi-annoying), there isn't special other being "pretty".

if really really need offline work, or behind proxies, else. gitextenions great integration windows context menus, , great repo manager, , not confusing add/stash/commit interface. reminds me of tortoisesvn.

msysgit option guis, bit more crude (it looks 16bit app'ish). personally, i'd rather use commandline it, thats me , choices.

oh, , lastly, in less 10 seconds , 1 google search, found how set ghfw work through proxy using standard .gitconfig
