+# svn-fast-info plugin
+
+Faster alternative to the main SVN plugin implementation. Works with svn 1.6 and newer.
+Use as a drop-in replacement to the svn plugin, not as complementary.
+
+To use it, add `svn-fast-info` to the plugins array in your zshrc file:
+
+```zsh
+plugins=(... svn-fast-info)
+```
+
+It's faster because it has an 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 `svn_prompt_info` method to display the svn repository status in your theme.
+
+## Functions
+
+- `svn_prompt_info`: displays all the available information regarding the status of the svn repository.
+
+- `svn_repo_need_upgrade`: shows whether the repository needs upgrading. `svn_prompt_info` queries the
+  rest of functions or not based on the result of this function.
+
+- `svn_current_branch_name`: shows the current branch.
+
+- `svn_repo_root_name`: displays the repository root.
+
+- `svn_current_revision`: shows the currently checked-out revision.
+
+- `svn_status_info`: shows a bunch of symbols depending on the status of the files in the repository.
+
+## Options
+
+- `ZSH_THEME_SVN_PROMPT_PREFIX`: sequence displayed at the beginning of the prompt info output.
+
+- `ZSH_THEME_SVN_PROMPT_SUFFIX`: sequence displayed at the end of the prompt info output.
+
+- `ZSH_THEME_SVN_PROMPT_CLEAN`: sequence displayed when the status of the repository is clean.
+
+- `ZSH_THEME_SVN_PROMPT_ADDITIONS`: sequence displayed if there are added files in the repository.
+  **Default:** `+`.
+
+- `ZSH_THEME_SVN_PROMPT_DELETIONS`: sequence displayed if there are deleted files in the repository.
+  **Default:** `✖`.
+
+- `ZSH_THEME_SVN_PROMPT_MODIFICATIONS`: sequence displayed if there are modified files in the repository.
+  **Default:** `✎`.
+
+- `ZSH_THEME_SVN_PROMPT_REPLACEMENTS`: sequence displayed if there are replaced files in the repository.
+  **Default:** `∿`.
+
+- `ZSH_THEME_SVN_PROMPT_UNTRACKED`: sequence displayed if there are untracked files in the repository.
+  **Default:** `?`.
+
+- `ZSH_THEME_SVN_PROMPT_DIRTY`: sequence displayed if the repository is dirty.
+  **Default:** `!`.
