Polyglot 1.4.46b
Michel Van den Bergh's Linux and Windows builds based on Fonzy Bluemers modification
of Fabien Letouzey's Polyglot with original work and bugfixes
- The default persistence directory on Windows is now _PG. The names of the
engine specific ini files are mangled so as not to contain spaces.
- PG now tries to guess if a string option is really a file or a path (like in
the Arena GUI).
