startpcsc is a simple utility used to force an instance to be launched
prior to running an application.  This is generally only needed to
ensure that USB readers are fully enumerated before an application
calls SCardListReaders() for the first time.

This is to help some applications which may not be designed to be
fully and dynamically hotplug aware.

Specifically startpcsc does the following:

1. Calls SCardEstablishContext()
2  Calls SCardReleaseContext()
3. startpcsc exits.

After startpcsc exits, the instance that services the client's
$DISPLAY will be running if it wasn't before, and the one running
will remain running if it was started prior to running startpcsc.
