Chris@0: // Desired options:
Chris@0: //
Chris@0: // * output preference:
Chris@0: //   - all data in one file
Chris@0: //   - one file per input file
Chris@0: //   - one file per input file per transform
Chris@0: //   - (any use for: one file per transform?)
Chris@0: //
Chris@0: // * output location:
Chris@0: //   - same directory as input file
Chris@0: //   - current directory
Chris@0: //
Chris@0: // * output filename: 
Chris@0: //   - based on input (obvious choice for one file per input file modes)
Chris@0: //   - specified on command line (obvious choice for all in one file mode)
Chris@0: //
Chris@0: // * output format: one or more of
Chris@0: //   - RDF
Chris@0: //   - AudioDB
Chris@0: //   - Vamp Simple Host format
Chris@0: //   - CSV
Chris@0: //
Chris@0: // * input handling:
Chris@0: //   - run each transform on each input file separately
Chris@0: //   - provide all input files to the same transform, one per channel
Chris@0: //
Chris@0: // * format-specific options:
Chris@0: //   - RDF format: fancy/plain RDF
Chris@0: //   - CSV format: separator, timestamp type
Chris@0: //   note: do the output file/location also count as format-specific options?
Chris@0: //   an output writer that wrote to a database would have different options...
Chris@0: //
Chris@0: // * debug level and progress output
Chris@0: // 
Chris@0: // * other potential options:
Chris@0: //   - ignore version mismatches in Transform specifications
Chris@0: //   - sample rate: force a given rate; use file rate instead of rate in
Chris@0: //     Transform spec
Chris@0: // 
Chris@0: // * other potential instructions:
Chris@0: //   - write out a skeleton Transform file for a specified plugin
Chris@0: //   - write out skeleton RDF for a plugin library (i.e. do the job of
Chris@0: //     RDF template_generator)
Chris@0: //   - verify that RDF for a plugin library matches the plugin
Chris@0: //
Chris@0: // MAYBE:
Chris@0: // * transform(s) to run:
Chris@0: //   - supply transform file names on command line
Chris@0: //   - use all transforms found in a given directory?
Chris@0: //
Chris@0: // MAYBE:
Chris@0: // * input files to transform:
Chris@0: //   - supply file names or URIs on command line
Chris@0: //   - use all files in a given directory or tree
