[sane-devel] Multiple Scanner Support

[Joel]

Neat. So far my experience with SANE is using it as a TWAIN plugin for Mac OSX's Image Capture. The text based commands seem much better than the gaudy manufacturer supplied GUIs though! Maybe I'll direct my future scanner purchases to SANE supported scanners. Into which program(s) do I input the pseudocode?
