+This is an efficient C++ implementation of the Cassowary constraint solving
+algorithm. Kiwi(solver) is an implementation of the algorithm based on the
+seminal Cassowary paper. It is not a refactoring of the original C++ solver.
+Kiwi(solver) has been designed from the ground up to be lightweight and fast.
+It ranges from 10x to 500x faster than the original Cassowary solver with
+typical use cases gaining a 40x improvement. Memory savings are consistently
+> 5x.

+# 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.
