usage_description="
Run a command for each Travis CI repo

All arguments become the command template

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

{username}, {user}    => your authenticated user / organization
{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}
"
