 If you’re in a hurry, see the examples below :). They should be reasonably self-explanatory.
 
-The configuration file comprises one or more *stream specifications* that tell the script how to chop up and combine the various podcast input sources. Timestamps are whitespace-delimited (space or newline), but whitespace is otherwise insignificant. Use # for comments.

-Stream specifications can appear in any order (except for `^` frame inputs, see below), but this will make the file harder to understand. We recommended grouping all stream specifications of the same type in chronological order. Each stream specification starts with an *input specification*, followed by zero or more *segment specifications*.

 Input specifications

 `num` is optional and represents either the `ffmpeg` stream number for audio and video inputs, or the frame/page number for frame inputs. It is zero-indexed (so page 1 of a PDF input is specified as 0). It defaults to 0 if omitted. For frame inputs, you can also specify `-1` or `last` to indicate that it should use the last frame of the input file (negative values other than -1 are currently not supported).

 These are normally just a sequence of timestamps, representing punch in and punch out times. Timestamps are in `HH:MM:SS[.ccc]` format. `HH` and `MM` are currently mandatory, but this will change soon to allow more flexibility. The punch out time for a segment *must* be later than the punch in time, but otherwise you can list timestamps in any order. However, we recommend listing them chronologically for the sake of sanity!
