Thanks, I didn't know about this -- However, for my particular example
of a broken snippet, it doesn't help. It just stops working with a
non-helpful error message when it gets to the kickstart with the problem:
Exception occured: <type 'exceptions.NameError'>
[etc]

Thanks again! This will probably help for some things. Still, it
doesn't appear to help with my example broken snippet. At least, not
when I did this:
#errorCatcher Echo
#if $break_me == 1
# no #end if...
I did notice that if you have an undefined variable, it changes the
behavior completely. Without errorCatcher, the kickstart would just have:
$SNIPPET('snippet_with_error')
but with errorCatcher, the kickstart is printed with the undefined
variable in it. Maybe this isn't a good thing, because there's no error
message anywhere I can find. i.e. all the errorCatcher does in this
case is make the error silent! At least when "$SNIPPET" is present I
know there's an error in it :)
