The purpose of yPlot (see our website at http://yplot.sourceforge.net and
our SourceForge project site at http://sourceforge.net/projects/yplot) is to
be a useful tool in creating scientific plots of both draft and publication
quality very quickly and efficiently.

yPlot attempts to meet this goal by providing a convenient front-end
(written as an extension to Yorick) for PLplot.   Yorick is a very fast
interpreted matrix language with a C-like syntax developed at Livermore.
PLplot is a mature plotting package (also hosted by SourceForge) that provides
all features required for publication-quality scientific plots.  Thus, yPlot
combines the power of Yorick with the high-quality plotting available from
PLplot.

Currently, a large subset of the most heavily used part of the PLplot API is
available from yPlot, and the current project goals are to extend yPlot
coverage to the entire PLplot API and also to keep up with the continuing
development of PLplot.
