-#### Lazy loading
-
-By default, virtualenvwrapper is loaded in lazy mode. This behaviour can be disabled adding the following line to *~/.zpreztorc*:
-
-    zstyle ':prezto:module:python' lazy_venv 'no'
-
-#### Automatic virtualenv initialization
-
-To enable autoenv, add the following line to *~/.zpreztorc*:
-
-    zstyle ':prezto:module:python' autoenv 'yes'
-
-If a virtualenv is active, and was not activated by autoenv, then autoenv does nothing.
-Otherwise, autoenv activated or deactivates a virtual environment whenever a directory is changed; based on the following priority:
-
-    1. Name specified in a file named *.venv* in the cwd.
-    2. *.venv* file in git root. If folder is inside git repository.
-    3. Name of git root folder.
-    4. No virtualenv.
