Lining up with the reversion of 70ec508e, also

check the ansible-module file back in.  This is basically to make things easier
to build from setup.py.

+.SH "NAME"
+ansible-modules \- stock modules shipped with ansible
+.SH "DESCRIPTION"
+.sp
+Ansible ships with a number of modules that can be executed directly on remote hosts or through ansible playbooks\&.
+.SH "IDEMPOTENCE"
+.sp
+Most modules other than command are idempotent, meaning they will seek to avoid changes unless a change needs to be made\&. When using ansible playbooks, these modules can trigger change events\&. Unless otherwise noted, all modules support change hooks\&.
+.SH "COMMAND"
+.sp
+The command module takes the command name followed by a list of arguments, space delimited\&. This is the only module that does not use key=value style parameters\&.
+.sp
+Example usage:
+.sp
+"/sbin/shutdown \-t now"
+.sp
+This module does not support change hooks\&.
+.sp
+Returns the return code from the program as well as timing information\&.
+.sp
+Async command running and command execution time limits are in plan\&.
+.SH "COPY"
+.sp
+The copy module takes a list of source files
+.PP
+\fBsrc=\fR
+.RS 4
+Local absolute path to a file to copy to the remote server
+.RE
+.PP
+\fBdest=\fR
+.RS 4
+Remote absolute path where the file should end up
+.RE
+.sp
+This module also returns md5sum information about the resultant file\&.
+.SH "FACTER"
+.sp
+Runs the discovery program \fIfacter\fR on the remote system, returning JSON data that can be useful for inventory purposes\&. It makes no changes on the remote system\&.
+.sp
+Requires that \fIfacter\fR and \fIruby\-json\fR be installed on the remote end\&.
+.sp
+This module takes no parameters & does not support change hooks\&.
+.SH "GIT"
+.sp
+Deploys software from git checkouts\&.
+.sp
+This module is in plan\&.
+.SH "OHAI"
+.sp
+Similar to the facter module, this returns JSON inventory data but makes no changes on the remote system\&.
+.sp
+Requires that \fIohai\fR be installed on the remote end\&.
+.sp
+This module takes no parameters & does not support change hooks\&.
+.SH "PING"
+.sp
+A trivial test module, this module always returns the integer \fI1\fR on successful contact\&. It makes no changes on the remote system\&.
+.sp
+This module does not support change hooks\&.
+.SH "SERVICE"
+.sp
+Controls services on remote machines\&.
+.PP
+\fBensure=\fR
+.RS 4
+Values are
+\fIstarted\fR,
+\fIstopped\fR, or
+\fIrestarted\fR\&. Started/stopped are idempotent actions that will not run commands unless neccessary\&.
+\fIrestarted\fR
+will always bounce the service
+.RE
+.PP
+\fBname=\fR
+.RS 4
+The name of the service
+.RE
+.SH "SETUP"
+.sp
+Writes a JSON file containing key/value data, for use in templating\&. Call this once before using the template modules, usually as the very first step in your playbook\&.
+.PP
+\fBmetadata=\fR
+.RS 4
+Optionally overrides the default JSON file location of /etc/ansible/setup\&. If used, also supply the metadata parameter to
+\fItemplate\fR\&.
+.RE
+.sp
+Does not support change hooks yet, but in plan\&.
+.SH "TEMPLATE"
+.sp
+Templates a file out to a remote server\&. Call the setup module prior to usage\&.
+.PP
+\fBsrc=\fR
+.RS 4
+path of a Jinja2 formatted template on the local server
+.RE
+.PP
+\fBdest\fR
+.RS 4
+location to render the template on the remote server
+.RE
+.PP
+\fBmetadata\fR
+.RS 4
+location of a JSON file to use to supply template data\&. Default is /etc/ansible/setup which can be easily created using the
+\fIsetup\fR
+module\&.
+.RE
+.sp
+This module also returns md5sum information about the resultant file\&.
+.SH "USER"
+.sp
+This module is in plan\&.
+.SH "YUM"
+.sp
+This module is in plan\&.
+.SH "WRITING YOUR OWN MODULES"
+.sp
+To write your own modules, simply follow the convention of those already available in /usr/share/ansible\&. Modules must return JSON but can be written in any language\&. To support change hooks, modules should return hashes, with a changed: True/False element at the top level\&. Modules can also choose to indicate a failure scenario by returning a top level \fIfailure\fR element with a True value\&.
+.SH "AUTHOR"
+.sp
+Ansible was originally written by Michael DeHaan\&. See the AUTHORS file for a complete list of contributors\&.
