application framework. This directory contains the following

<dd>Source code for the event mechanism for the cross-platform application
framework. This code contains the machinery to do key bindings,
mouse bindings, menu bars, and tool bars. This code is
currently used by the word processor, but we expect to also use
it for the spreadsheet application.</dd>
