Subject: Just for Gareth: a means of overriding individual game colour
X-Git-Url: http://www.chiark.greenend.org.uk/ucgi/~ian/git?a=commitdiff_plain;h=b77d727eb4a822d3ee70b6c5e0949e76e6def5ea;p=sgt-puzzles.git

Just for Gareth: a means of overriding individual game colour
settings using environment variables. GTK frontend only, because
this is an unsupported (and unprincipled) hack.
