Word Unperfect - XT-Emporium

File editor

# libc-only Unix build for word unperfect.
#
# This folder intentionally does not compile or modify the DOS/OpenWatcom build
# harness or runtime adapter.  Normal file/print/export paths use ISO C stdio.
# The default Linux TUI links the shared frontend's Unix terminal adapter so the
# host build starts in the same full-screen editor mode as the DOS clone.
