+ # Examine the RCS history and generate a data structure for
+ # the recentchanges page.
+ # This structure is a list of items, each item is a hash reference
+ # representing one change to the repo.
+ # The hash has keys user (a link to the user making the change),
+ # committype (web or the name of the rcs), when (when the change
+ # happened, relative to the current time), message (a reference
+ # to an array of lines for the commit message), and pages (a
+ # reference to an array of links to the pages that were changed).
