Paced (Predictive Abbreviation Completion and Expansion using Dictionaries) scans a group of files (determined by "population commands") to construct a usage table (dictionary). Words (or symbols) are sorted by their usage, and may be later presented to the user for completion. A dictionary can then be saved to a file, to be loaded later. Population commands determine how a dictionary should be filled with words or symbols. A dictionary may have multiple population commands, and population may be performed asynchronously. Once population is finished, the contents are sorted, with more commonly used words at the front. Dictionaries may be edited through EIEIO's customize-object interface. Completion is done through `completion-at-point'. The dictionary to use for completion can be customized.
