33 dnl This is a simple configuration-script for the ncurses test programs that
34 dnl allows the test-directory to be separately configured against a reference
35 dnl system (i.e., sysvr4 curses)
36 dnl
37 dnl If you're configuring ncurses, you shouldn't need to use this script.
38 dnl It's only for testing purposes.
