Subject: Add -men option for changing piece moves
X-Git-Url: http://winboard.nl/cgi-bin?p=xboard.git;a=commitdiff_plain;h=2087ac0f61e84f7f71cbea5a0a3325374f9e76ee

Add -men option for changing piece moves

A volatile string option -men allows the user to change the moves of
the pieces from the command line similar to what the VariantMen tag
does from a PGN file. Using the New Variant dialog resets the option.
