+# Test .emb to ensure that the import system works.

+# The file imported_genfiles.emb is identical to imported.emb except for the
+# [(cpp) namespace] attribute; it is used to ensure that generated .embs can be
+# used by the emboss_cc_library build rule.
+
+# These imports intentionally use names that do not match the file names, as a
+# test that the file names aren't being used.
