A very generous French patron was kind enough to share a TON of information, manuals, disk images and notes about a utility cartridge for the Commodore 64 called "The Tool 64".  Inside this archive is ful documentation in French, Swedish and some in English.  There is also a disk image of The Tool 64 as well as information and documentation on an extension to this cartridge that adds even more commands to BASIC.

Updated - Now includes the .crt image also.
