+module: fetch
+short_description: Fetches a file from remote nodes
+description:
+     - This module works like M(copy), but in reverse. It is used for fetching
+       files from remote machines and storing them locally in a file tree,
+       organized by hostname. Note that this module is written to transfer 
+       log files that might not be present, so a missing remote file won't
+       be an error unless fail_on_missing is set to 'yes'.
+version_added: "0.2"
+options:
+  src:
+    description:
+      - The file on the remote system to fetch. This I(must) be a file, not a
+        directory. Recursive fetching may be supported in a later release.
+    required: true
+    default: null
+    aliases: []
+  dest:
+    description:
+      - A directory to save the file into. For example, if the I(dest)
+        directory is C(/backup) a I(src) file named C(/etc/profile) on host
+        C(host.example.com), would be saved into
+        C(/backup/host.example.com/etc/profile)
+    required: true
+    default: null
+  fail_on_missing:
+    version_added: "1.1"
+    description:
+      - Makes it fails when the source file is missing.
+    required: false
+    choices: [ "yes", "no" ]
+    default: "no"
+examples:
+   - code: "fetch: src=/var/log/messages dest=/home/logtree"
