"""gp -- a platform-independent interface to a gnuplot process.
This file imports a low-level, platform-independent interface to the
gnuplot program. Which interface is imported depends on the platform.
There are variations of this file for Unix, the Macintosh, and for
Windows called gp_unix.py, gp_mac.py, and gp_win32.py, respectively.
Note that the end-user should use the more capable interface from
__init__.py (i.e., 'import Gnuplot') rather than the low-level
interface imported by this file.
See gp_unix.py for most documentation about the facilities of the
gp_*.py modules.
