Subject: Use setup command in Sho Shogi
X-Git-Tag: 0.18~21
X-Git-Url: http://winboard.nl/cgi-bin?a=commitdiff_plain;h=5bb5207f5d6a946c0e45cd458c66ed9010d21995;p=hachu.git

Use setup command in Sho Shogi

To exploit the new engine-defined-variants mechanism of XBoard,
a duplicate of Sho Shogi is added with an engine-defined name.
The length of the variant table is now determined dynamically,
by using the sentinel, and the variants feature is now generated from
this table (rather than hard-coded). The variant 12x12+0_fairy has
been dropped as alternative for Chu Shogi, as this never really worked,
and chu has been elevated to standard variant in the XBoard main branch.
