+description: >
+     Executes a low-down and dirty SSH command, not going through the module
+     subsystem. This is useful and should only be done in two cases. The first
+     case is installing python-simplejson on older (python 2.4 and before)
+     hosts that need it as a dependency to run modules, since nearly all core
+     modules require it. Another is speaking to any devices such as routers
+     that do not have any Python installed. In any other case, using the
+     'shell' or 'command' module is much more appropriate. Arguments given to
+     'raw' are run directly through the configured remote shell and only output
+     is returned. There is no error detection or change handler support for
+     this module
+examples:
+    - code: ansible newhost.example.com -m raw -a "yum -y install python-simplejson"
+      description: Example from /usr/bin/ansible to bootstrap a legacy python 2.4 host

+short_description: Gathers facts about remote hosts
+description: >
+     This module is automatically called by playbooks to gather useful
+     variables about remote hosts that can be used in playbooks. It can also be
+     executed directly by /usr/bin/ansible to check what variables are
+     available to a host. Ansible provides many 'facts' about the system,
+     automatically.
+notes: >
+    More ansible facts will be added with successive releases. If facter or
+    ohai are installed, variables from these programs will also be snapshotted
+    into the JSON file for usage in templating. These variables are prefixed
+    with facter_ and ohai_ so it's easy to tell their source. All variables are
+    bubbled up to the caller. Using the ansible facts and choosing to not
+    install facter and ohai means you can avoid ruby-dependencies on your
+    remote systems.
+examples:
+    - code: ansible all -m setup -tree /tmp/facts
+      description: Obtain facts from all hosts and store them indexed by hostname at /tmp/facts.
