Xvi is a portable multi-window version of `vi'. In spite of its name,
there is, as yet, no X-Windows-specific version of it, but work is
still in progress. Existing versions use text windows separated by
horizontal status lines on character mode displays. The windows may
represent different files being edited, or different views on to the
same file.
Unix, MS-DOS and QNX versions have now been in regular use by the
authors, and many of our colleagues, for about three and a half years,
and the editor's behaviour seems fairly satisfactory.
