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