I don't get this because I'm on a Mac, which isn't very strict on
capitalization/non-capitalization of file and directory names. Need to see
where this typo is. Also need to change from gism to gismgr or something
like that.

Right now, all actions are very 'noisy', producing lots of messages in the
terminal

I'll have to try and see what's up with this.

These should be fixable with better error-trapping in select.Select.

This happens when any map is first added. Part of the 'noisy' output. The
map can't be rendered until all information is complete. You can ignore it,
but we should track it down anyway.

I don't understand the problem here. It is not happening on my system. Can
someone else check this out? This is not a version problem, and I don't know
what is wrong.

Yes. This is a consequence of just using the autogenerated command dialogs
for setting options at the moment. If you want to set options for a layer,
you need to open the options dialog for that layer, set the options, and
close the dialog. Repeat to set options for another layer. Also, if you want
to change options, you have to start over with an empty options dialog. This
is pretty clunky, but it was a fast way to make some kind of layer options
setting available. Clearly this needs to be considerably more sophisticated.
Thanks for the comments.
