I think that Hiracs uses the experience and (general) knowledge of the former X-Chess developer. Conversely, if one distributes copies of the work without abiding by the terms of the GPL (for instance, by keeping the source code secret), he or she can be sued by the original author under copyright law. One is only required to adhere to the terms of the GPL if one wishes to exercise rights normally restricted by copyright law, such as redistribution. Because a GPL work is copyrighted, a licensee has no right to redistribute it, not even in modified form (barring fair use), except under the terms of the license. It earns its legal power from the use of copyright on software programs. When someone distributes a GPL'd work plus his/her own modifications, the requirements for distributing the whole work cannot be any greater than the requirements that are in the GPL. The distribution rights granted by the GPL for modified versions of the work are not unconditional.

PS: For those windows-users: it might be a good idea to look into cygwin ( ) to bring the power of the commandline to windows.HCE has been updated to version 1.8, both for Windows and OSX. Using a combination of simple Unix commands and pgn-extract would be still useful even if big databases were supported. These steps circumvent Hiarcs lack of big database support. PGN-EXTRACT by David Barnes ( ) is a fantastic command line tool to generate smaller databases for your openings. I have looked and there does not seem to be any specific incident mentioned in forums and in the official USCF groups that explains why this decision was made. For example you can download all TWIC pgn files, then navigate with the terminal to this directory, eg:Īnd then simply combine them with the cat command: Looks good, except that it makes the same opening moves every time Always Nf3 with white and d5 as black against e4. A handful of unix commands make the creation of a masterdatabase very easy. In Macs and of course in Linux the terminal can be used easily and to great effect. I find it a bit cumbersome to open a sophistaced GUI such as Chess Explorer just to combine databases. Pgn files are just well organized text files.
