# DVX GUI  -- Top-level Makefile
#
# Builds the full DVX stack: core library, task switcher,
# bootstrap loader, text help library, widgets, shell, and apps.
#
# Source tree mirrors bin/ layout:
#   src/libs/kpunch/<libname>/   -> bin/libs/kpunch/<libname>/<libname>.lib
#   src/widgets/kpunch/<widget>/ -> bin/widgets/kpunch/<widget>/<widget>.wgt
#   src/apps/kpunch/<app>/       -> bin/apps/kpunch/<app>/<app>.app
#   src/loader/                  -> bin/DVX.EXE
#   src/tools/                   -> bin/host/<tool>

# Libraries are discovered, never listed: every src/libs/kpunch/<name>/
# with a Makefile is one.  Run-time load order comes from each library's
# .dep file; the build only needs the core libraries first (and the shell
# before the task manager, which links against it).
