Re: Blind people using setup.exe?

[Nikhil Nair <nnair at pobox dot com>]

Dear all,

On balance, I've now decided to chicken out and leave the mouse
manipulation stuff... Ivor, you were quite right - if nothing else,
finding a drawn line between two columns etc. is probably not doable.

However, Ivor's trick of inserting package information with a 0-0 version
number seems to work excellently - doing this for gcc brought in all the
dependencies.

I've written a short script which does the honours for a list of packages
given on the command line, checking they're not already installed.
Installing gcc simply involved:

$ addpkg.sh gcc
$ cygstart [...]/setup.exe

and then accepting most of the defaults (I just pressed enter when I
reached the chooser screen).

I enclose the script below, in the hope that it might be useful to
others, blind or not.

Cheers,

Nikhil.
