String Utilities
****************

Toolkit for various string activity.

Changed in version 1.3.0: Dropped the get_* prefix from several
function names. The old names still work, but are deprecated aliases.

**Module Overview:**

   crop - shortens string to a given length

   size_label - human readable label for a number of bytes
   time_label - human readable label for a number of seconds
   time_labels - human readable labels for each time unit
   short_time_label - condensed time label output
   parse_short_time_label - seconds represented by a short time label
