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}
