+ContourPy is a Python library for calculating contours of 2D
+quadrilateral grids.  It is written in C++11 and wrapped using pybind11.
+
+It contains the 2005 and 2014 algorithms used in Matplotlib as well as
+a newer algorithm that includes more features and is available in both
+serial and multithreaded versions.
+
+NOTE: This is intended to be installed mainly as a dependency for newer
+      matplotlib versions. Thus, presently just the core functionality
+      is provided, since additional features, i.e. the bokeh renderer,
+      need optional dependencies, which are not yet available through
+      SlackBuilds.org. This might change in the future.

+# HOW TO EDIT THIS FILE:
+# The "handy ruler" below makes it easier to edit a package description.
+# Line up the first '|' above the ':' following the base package name, and
+# the '|' on the right side marks the last column you can put a character in.
+# You must make exactly 11 lines for the formatting to be correct.  It's also
+# customary to leave one space after the ':' except on otherwise blank lines.
