+// 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
