+# Faster alternative to the current SVN plugin implementation.
+#
+# Works with svn 1.6, 1.7, 1.8.
+# Use `svn_prompt_info` method to enquire the svn data.
+# It's faster because his efficient use of svn (single svn call) which saves a lot on a huge codebase
+# It displays the current status of the local files (added, deleted, modified, replaced, or else...)
+#
+# Use as a drop-in replacement of the svn plugin not as complementary plugin
