NOTE:
To avoid confusion with original programs comming with Solaris 10,
spline, plot and their man pages are prefixed with a "g". So you should
use gspline or ggraph or 'man ggraph' and 'man gspline' respective, if you
want to use the GNU version of these utilities.

Furthermore include files have been moved to the include/plotutils
subdirectory. If you want to compile programs, which require the GNU plotutils
libraries, make sure to add an appropriate CFLAG option like
-I /usr/include/plotutils. If you want to use the original aka system version
of libplot, make sure to link against the system libplot library.
