[Cin] old script - mkframelist

I wonder if this old script still works (should make Cinelerra framelist for dir full of images) and if so - can it be included in 'contrib' folder of source tree (because hunting it via google or reimplementing each time one need to make 'list of images' input file for Cin... a bit counterproductive?) not sure about license - this is just support script, not linked to binary and not requred for main editing operations - but still useful IMO for working with image files generated by some other program
