The only program (as of last year) was PRESRED, which is a dinosaur BASIC program from the late '80s. I use it out of necessity, but have also developed a spreadsheet which I use. PRESRED is freeware, I believe, but I couldn't find a download site.
I talked to Dr. Briaud at A&M last year about the possibility of a new program.....nothing is in the works right now, but he would expressed interest in putting one together. I don't have enough programming knowledge to attempt such a thing though.
I'll track down my copy of presred, and make sure it is distributable. I could email it to you if it is.
