This is the SANKit project ("sankit")
This project was registered on SourceForge.net on Nov 30, 2010, and is described by the project team as follows:
SAN Kit was made public in 1993 by Stephen Edwards, the inventor of PGN Chess notation. The original code is in C, and with few comments quite cryptic. In addition, the original author's style was quite quixotic, making it even more difficult to read. This code is now reformatted to modern standards, adds support for NAG codes and comments, and has a "non-CLI" mode for inclusion in chess playing programs. The code has gone through extensive analysis using the llvm/clang compiler and reports no issues at this time. To use the code as a "framework" you would undefined "CLI". In addition, a small C++ program is included that takes as input a file of one or more PGN records, and outputs pure pristine PGN records as output. In addition to flagging errors at the move level, the program provides three boards around the move. NOTE: plan on budgeting a fair amount of time to read, re-read, and experiment with the documentation and cryptic uncommented code. You are on your own
