This index links directly to the manual on inform-fiction.org. If you want, you can download this version of the index and put it in the same directory as a local copy of the file. This matches the PC version; it is off by one for the Mac (to be fixed at some point).

The index was built from this toolkit for Windows. It requires a version of the documentation which includes a "manifest.txt" file, which did not exist for versions 3K56 and earlier, but should exist for future versions.
