Subject: Install engines as ./exefile in XBoard
X-Git-Url: http://winboard.nl/cgi-bin?a=commitdiff_plain;h=95772c234f0afaf88ef01854868c93ff2e8a20fb;p=xboard.git

Install engines as ./exefile in XBoard

When a path name is split into directory and filename, the latter in Linux
must be preceded by ./ in order to make it executable in the directory
XBoard starts it in.
