# This script creates a CGAL makefile with entries for all .C files in the
# current directory.
#
# Usage: create_makefile [-options] [outputfile]
#
# -d   create a default CGAL makefile
# -t   create a makefile for the test suite
# -w   create a makefile with flags for LEDA windows
# -g   create a makefile with flags for GEOWIN
# -q   create a makefile with support for QT
