By default, configure will automatically choose the first valid value it finds
for each option. You can set it to interactive to find all possible values and
give you a choice:
    ''' + font.blue( 'make config interactive=1' ) + '''

If you have multiple compilers, we suggest specifying your desired compiler by
setting CXX, as the automated search may prefer a different compiler.

For ANSI colors, set color=auto (when output is TTY), color=yes, or color=no.

See INSTALL.md for more details.
