+  Numba translates Python functions to optimized machine code at
+runtime using the industry-standard LLVM compiler library.
+Numba-compiled numerical algorithms in Python can approach the
+speeds of C or FORTRAN.
+
+  You don't need to replace the Python interpreter, run a separate
+compilation step, or even have a C/C++ compiler installed. Just apply
+one of the Numba decorators to your Python function, and Numba does
+the rest.

+# 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.
