How do I use it?

% cd some_project_in_git
% github-import --username jrockway --password whatever --add-remote --push-mode all

You can also create a config file. Here is an example using a real man's editor:

% cat > ~/.github-import
---
username: jrockway
password: ilovehellokitty
remote:   origin # if you don't like "github"
^D
% cd some_other_project_in_git
% github-import
