# Build utilities for FLTK development

# and not installed. They are tools used to generate source files or
# assist in building documentation.

# cmap - colormap generation program

# This program produces the contents of "src/fl_cmap.h".
# It can be used to modify the built-in colormap in src/fl_cmap.h.
# This utility must be built and executed manually. See instructions
# in util/cmap.cxx .

# but it requires libm on Unix/Linux - link against libm, but only if found.
