usage_description="
Run a command for each Buildkite pipeline

All arguments become the command template

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

{username}, {user}      => \$BUILDKITE_ORGANIZATION / \$BUILDKITE_USER
{organization}, {org}   => \$BUILDKITE_ORGANIZATION / \$BUILDKITE_USER
{name}                  => the pipeline name without the user/organization prefix
{pipeline}              => the pipeline name with the user/organization prefix

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