+== Logging warnings
+When EXIF information is malformed, a warning is logged to STDERR with
+the standard Ruby logger.  Log to some other location by supplying an
+alternative implementation:
+
+  EXIFR.logger = SyslogLogger.new
+
+== Time zone support
+EXIF does not support time zones so this code does not support time
+zones.  All time stamps are created in the local time zone with:
+
+  Time.local(..)
+
+It is possible to change this behavior by supplying an alternative
+implementation.  For those who prefer UTC:
+
+  EXIFR::TIFF.mktime_proc = proc{|*args| Time.utc(*args)}
+
+Or when the application depends on ActiveSupport for time zone handling:
+
+  EXIFR::TIFF.mktime_proc = proc{|*args| Time.zone.local(*args)}
