very cool! any superfancy algorithms you're using? i could assist porting
it to c where we read all the image formats we need to give you more
precision. i can also help out writing a gnuplot table to dt basecurve
preset program.

cheers,
 jo

Get your SQL database under version control now!
Version control is standard for application code, but databases havent
