Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Generate text documentation from the troff source files. This is done by make, in the 'docs' target, which is now part of the normal build process. Unfortunately, not all the games include troff sources. Getting decent HTML output from groff is still a difficult process which will not be attempted at this time. There are a few bugs in the 'install' and 'uninstall' rules. Not to mention that the documentation is sometimes inaccurate.
