Comment (by ctreleaven):

 Will do on the first two points.

 The long_description shows on the first installer splash screen.  I've
 found it useful to confirm the prefix that the payload is going to be
 installed into.  One of the most common questions I get about my
 installers is: "where did everything go?".

 I'll update the patch shortly.  Do you want to a) apply the patch, b) deal
 with a pull request or c) let me commit (er, push) the change?  ;)
