usage_description="
Run a command for each original non-fork GitHub repo

All arguments become the command template

\$GITHUB_ORGANIZATION / \$GITHUB_USER - the user or organization to iterate the repos on - if not specified then determines the currently authenticated github user from your \$GITHUB_TOKEN

The command template replaces the following for convenience in each iteration:

{organization}, {org} => the organization account being iterated
{username}, {user}    => the user account being iterated
{name}                => the repo name without the user prefix
{repo}                => the repo name with the user prefix

eg.
    ${0##*/} echo user={user} name={name} repo={repo}
    ${0##*/} echo org={org}   name={name} repo={repo}
