+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You

+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and

+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,

+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.

+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this

+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.

+ansible-keepalived: Ansible role for setting up keepalived 
+============================================================
+Toni Comerma - tcomerma (at) gmail.com
+
+This role sets up keepalived for an standard setup of:
+  - One virtual IP
+  - Two hosts
+
+You just need to provide an small amount of information to have it running
+  - Add "keepalived" role to both hosts
+  - Add variable keepalived_role: "master" | "slave" to the appropiate hosts 
+  - Add variable keepalived_shared_ip: "floating IP address" to both hosts
+
+Other variables can be configured, overwriting defaults/main.yml
+
+Keepalived can watch processes to influence on which node should be the master. Setting
+variable "keepalived_check_process" to the name of the process will do. I use keepalived
+to give high availability to haproxy, so I use.
+
+keepalived_check_process: "haproxy"
+
+Dependencies
+------------
+Works with centos/redhat and Debian/Ubuntu
+
+Role Variables
+--------------
+	keepalived_auth_pass: "1111"
+	keepalived_role: "MASTER"
+	keepalived_router_id: "52"
+	keepalived_shared_iface: "eth0"
+	keepalived_shared_ip: "192.168.1.1"
+	keepalived_check_process: "keepalived"
+	keepalived_priority: "100"
+	keepalived_backup_priority: "50"
+
+Example Playbook
+-------------------------
+
+    - hosts: s1
+      roles:
+         - { role: keepalived, keepalived_shared_ip: "192.168.1.1", keepalived_role: "master" }
+
+    - hosts: s2
+      roles:
+         - { role: keepalived, keepalived_shared_ip: "192.168.1.1", keepalived_role: "slave" }
+
+
