As of version 16, all Fractint documentation is available online.
Run Fractint and press F1 for the main help index.

If you want a full documentation file (nicely formatted with table
of contents and cross-references by page number), you can easily
create one.
For the MS-DOS version, type the following command at the DOS prompt:
fractint makedoc
The above command will overwrite the file you are now reading
(fractint.doc) with the full Fractint documentation.

For the Unix version, type:
make doc
