+ * Change the meaning of EXTRAVERBOSE; previously, it was a y/n option
+ to make things more verbose. Add extra levels of verbosity (0, 1, 2 so
+ far) and a new vvecho() function for callers to use.
+ * With EXTRAVERBOSE==2 or more, make run_command() print out each
+ command as it's run. (Closes issue 39).
+ * If we don't find any CDDB or Musicbrainz information for the CD, try
+ to extract CD-Text information to populate the cddbinfo template.
+ (Closes issue 41).
+ * Try to give more helpful error messages when we can't parse the
+ command line, and exit rather than carry on. (Closes issue 51).
