+# Sorts out support for multiple window ports (interfaces) to included in the build.
+#
+# Included from:
+#           hints/linux.370
+#           hints/macOS.370
+#
+# The following will be set appropriately following this:
+#     - WANT_WIN_XXX  (at least one will be set; default is TTY)
+#     - WANT_DEFAULT (set to match one of the enabled WANT_WIN_XXX)
+#     - WINCFLAGS
+#     - WINSRC
+#     - WINOBJ0
+#---
+# User selections could be specified as combinations of any of the following:
+# WIN_WANT_TTY=1, WIN_WANT_CURSES=1, WIN_WANT_QT=1, WIN_WANT_X11=1
+# The selections will all be linked into the same binary.
+#
+# Assuming you have the prerequisite packages mentioned above, you can
+# specify, right on the make command line, which window ports (or interfaces)
+# to include in your build. Doing it via the make command line means that won't
+# have to edit the Makefile.
+#
+# make WANT_WIN_QT=1 WANT_WIN_X11=1 WANT_WIN_CURSES=1 WANT_WIN_TTY=1 install
+#
+# Add WANT_DEFAULT=Qt (or other interface) if you want nethack to use
+# something other than tty as the default interface.
