UUTool
UUTool[1] was a freeware application written for the Apple Macintosh by Bernie Wieser. The purpose of UUTool was to uuencode and uudecode files, however, the application functionality grew to translate uLaw encoded files[2] to AIFF format, segment large uuencoded files, and recombine multiple uuencoded files for decode.
Technical Details
UUTool uuencoded files and attached the .uu extension. However, UUTool was the first Macintosh program that encoded the data fork, resource fork, and finder information into one uuencoded file[3] with the .mu extension. The format for this was to catenate the three pieces of file information and uniquely name the resource fork and finder info as files. This allowed for some interoperability on non-Macintosh platforms.
Example
begin 0700 myfile ... end begin 0700 .rsrc ... end begin 0700 .finfo ... end
Trivia
- UUTool was written in C and hand-optimized 68K assembler for speed in the encoding and decoding process, taking advantage of fewer cycles to process a 32 bit data word (4 bytes) as opposed to character by character.
- The engine for UUTool also existed in a code resource to be incorporated into other programs.
- UUTool functioned on MacOS System 6.x through to 9.x. (Mac OS X 10.x has unix tools bundled as it was based on the Mach kernel.)
