Subject: Implement kludge to set options through Move Type-in
X-Git-Url: http://winboard.nl/cgi-bin?a=commitdiff_plain;h=d3c211c5c2ebfb2e77a6dc37c973ce7d69f301fd;p=xboard.git

Implement kludge to set options through Move Type-in

A leading "!!! " will cause the rest of the line to be parsed as
command line. Very dangerous, as an unknown option (e.g. because of a typo)
will cause a fatal error, which makes XBoard exit.
