v0.2.0

What's New

• Exposes get_options_env() (currently experimental), for the purpose of
  accessing a listing of option names. (@dgkf #17)

• Adds an optional option_fn parameter to option_spec, allowing for the
  stored option values to be processed, or to produce side-effects when
  accessed. (@dgkf #12)

Note

Bug Fixes

• Fixes opts(), which would previously return default values after being
  updated. Will now appropriately return values just as they would be fetched
  using opt(). (@dgkf #17)

Caution

Breaking Changes

• The result of opt_source() when a value is derived from an environment
  variable was changed from "envir" to "envvar" to be more consistent with
  the rest of the package's messaging about sources. (@dgkf #12)
