+[Cython][] is a Python-like language that makes it easy to write
+[[C]]-based extensions for [[Python]].  This is a Good Thing™, because
+people who will write good Python wrappers will be fluent in Python,
+but not necessarily in C.  Alternatives like [[SWIG]] allow you to
+specify wrappers in a C-like language, which makes thin wrappers easy,
+but can lead to a less idomatic wrapper API.  I should also point out
+[ctypes][], which has the advantage of avoiding compiled wrappers
+altogether, at the expense of dealing with linking explicitly in the
+Python code.
+
+The [Cython docs][docs] are fairly extensive, and I found them to be
+sufficient for writing my [[pycomedi]] wrapper around the [[Comedi]]
+library.  One annoying thing was that Cython does not support
+`__all__` ([cython-users][]).  I took [a stab at fixing this][github],
+but got sidetracked cleaning up the Cython parser ([cython-devel][],
+[later in cython-devel][later]).  I must have bit off more than I
+should have, since I eventually ran out of time to work on merging my
+code, and the Cython trunk moved off without me ;).
