# 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
