Hi All,

This is a reposting of a mail I sent to cygwin@cygwin.com - more 
appropriate to cygwin-apps.

I'm a novice at C++, so I'm quite likely to have declared something 
incorrectly. I also couldn't see how to make the command line option set 
the default selection - which would be a more elegant method.

Had thought about that, but I didn't see how to specify two repositories 
on the command line - and I didn't fancy having to run an httpd to serve 
a few files when it seemed like a useful thing for setup to do from the 
command line.

(As an aside, I've installed a dozen or so machines with this setup now, 
silently and with all the packages I need - I find the patch useful so I 
hope someone would be willing to polish / advise me how to polish it so it 
could be included in the 'official' version).

Yours,

Frank
