SGFC is the reference implementation for the SGF FF standard.
It's a command line tool for checking SGF files for correctness and correcting any errors. It also converts FF-FF files to FF.
SGFC is intended to be a tool for SGF experts, coders and maintainers of large SGF archives.
... [More] You ought to have quite some knowledge of SGF to use SGFC efficiently.
SGFC was written primarily for Go/WeiQi/Baduk (GM) files. It can't handle other games yet, i.e. it doesn't check any game-specific properties and values of other games than Go. It may even save errornous game-specific properties of other games! Use SGFC for other games with care. [Less]
