Not sure what this app is actually doing

Is there somehwere that one can find a user manual? I see that it is processing and tells me that the process is complete and how much the RAW file was and how much the new JPEG file is, but I have no idea where this converted down JPEG file resides. I have the same original RAW image in place with an added keyword stating "RawHide Original". I see no evidence of the supposed "RawHide Processed" tagged JPEG that, according to the descripion of the apps functions, is supposed to populate in the same project as the original. Not only is it not in the project it is nowhere to be found in my Aperture library.
