+Run a command in all virtualenvs under WORKON_HOME.
+
+Syntax::
+
+    allenvs command with arguments
+
+Each virtualenv is activated, bypassing activation hooks, the current
+working directory is changed to the current virtualenv, and then the
+command is run. Commands cannot modify the current shell state, but
+can modify the virtualenv.

+::
+
