xdata implements an interface to arbitrary key-value pairs which are accessible
to simple shell and Perl programs. Applications for this include to-do lists,
contact databases, browser bookmarks, and anything else which requires small
pieces of data to be referenced by keys. xdata stores timestamps for the data
it manages, and comes with a program to synchronise databases among cooperating
hosts. This allows you to propagate information among hosts in a transparent
fashion (creations, updates, and deletes are correctly handled). xdata
consists of a set of shell-level utilities and a Perl module.
