+The numexpr package evaluates multiple-operator array expressions many times
+faster than NumPy can. It accepts the expression as a string, analyzes it,
+rewrites it more efficiently, and compiles it to faster Python code on the
+fly. It's the next best thing to writing the expression in C and compiling
+it with a specialized just-in-time (JIT) compiler, i.e. it does not require
+a compiler at runtime.
+
+Also, and since version 1.4, numexpr implements support for multi-threading
+computations straight into its internal virtual machine, written in C. This
+allows to bypass the GIL in Python, and allows near-optimal parallel
+performance in your vector expressions, most specially on CPU-bounded
+operations (memory-bounded were already the strong point of Numexpr).
+
+This requires numpy.

+# 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 ':'.
