+# There was a bug that affected the `Translate()` when no targets were provided
+# explicitelly via argument list. If, for exapmle, `pkg1/SConscript` and 
+# `pkg2/SConscript` scripts in some project `p1` had:
+#
+#       Translate(LINGUAS_FILE = 1)
+#
+# then target languages defined in `pkg1/LINGUAS` would affect the list of
+# target languages emitted by `pkg2/SConscript` and vice versa.
+#
+# The pull request #64 on bitbucket fixes this. Here is the test case to
+# replicate the bug.
