v0.2.0

Added

• A constant string Error type

Changed

• String errors from errors.errorString variables to constants of our own Error type:

  • ErrEmptyCorpus
  • ErrInconsistentArgCount
  • ErrMalformedEntry
  • ErrUnsupportedVersion

  Although this has no practical effect on the operation of the package (apart from a negligible performance boost), it now prevents any code attempting to redefine them to other values from compiling.

• The formatting of the exit status code table in README.
