+# An experiment in using tox to install the sdist, and do the pytracer/ctracer
+# split.  Doesn't yet work because the working tree is in the import path, so
+# "import coverage" finds the working tree instead of the sdist-installed code.
+# This can be fixed one of two ways:
+#
+# 1. By changing to a "src" layout, so that "import coverage" won't work in the
+# working tree, or 
+#
+# 2. By removing the "__init__.py" from the tests directory, so that nose won't
+# add the working tree to the path. This will also mean changing a number of
+# import statements in the tests directory.
