long_description \
	The PGPLOT Graphics Subroutine Library is a Fortran- or C-callable, \
	device-independent graphics package for making simple scientific \
	graphs.  It is intended for making graphical images of publication \
	quality with minimum effort on the part of the user. For most \
	applications, the program can be device-independent, and the output can \
	be directed to the appropriate device at run time.
