# DVX, the DOS desktop JoeyLib's dvx port runs in: its SDK (the headers,
# sdk.mk and the host tools every DVX program is built with) and the runtime
# tree the gates and joey-run boot (dvx.exe with its libraries, widgets,
# programs, settings and system files). Copied from a built DVX tree, so the
# builds and the emulator runs never touch the DVX project itself.
#
# `install.sh --dvx-dir PATH` names the DVX tree (remembered); the default is
# a dvxgui checkout beside this repository. Rebuilding DVX there makes this
# component out of date, and `install dvx` copies it again.

# it out; `install dvx` (or toolchain:dvx) asks for it.
