+# This a theme for oh-my-zsh. Features a colored prompt with a right prompt 
+# containing the git status (if applicable).
+# The '%' prompt will be green if last command return value is 0, yellow otherwise.
+# The hostname color is based on hostname characters (see below).
+# When using as root, the left prompt shows only the hostname in red color.
