+ASCII CSV file may be loaded into a spreadsheet or database application, or
+processed by a program to transform the MIDI data (for example, to key
+transpose a composition or extract a track from a multi-track sequence).  A
+CSV file in the format created by midicsv may be converted back into a
+standard MIDI file with the csvmidi program.")
