+# This is a package that contains a number of modules that are used to
+# test import from the source files that have different encodings.
+# This file (the __init__ module of the package), is encoded in utf-8
+# and contains a list of strings from various unicode planes that are
+# encoded differently to compare them to the same strings encoded
+# differently in submodules.  The following list, test_strings,
+# contains a list of tuples. The first element of each tuple is the
+# suffix that should be prepended with 'module_' to arrive at the
+# encoded submodule name, the second item is the encoding and the last
+# is the test string.  The same string is assigned to the variable
+# named 'test' inside the submodule.  If the decoding of modules works
+# correctly, from module_xyz import test should result in the same
+# string as listed below in the 'xyz' entry.
