Re: Doc-enhancement for Setting automatic beam behaviour

[Ralph Palmer]

Hi -

I've run out of time - I just spent about an hour trying to figure out how
to mount two different versions on my laptop. I think I've figured it out,
but haven't implemented it yet. I tried running Urs' file under 2.12.2, and
got errors :
error: unknown escaped string: `\overrideBeamSettings'
Could this be related to 2.12 vs 2.13?

Next Bug Squad member, please take over. I'll work on getting 2.13 mounted
alongside 2.12.

Ralph
