+<div>
+  For some repository URL (such as <tt>scpexe</tt>), Maven may require
+  additional configuration (such as user name, executable path, etc.)
+
+  Maven wants you to specify this in <tt>~/.m2/settings.xml</tt> of
+  the user that runs Hudson, and this ID value is used to retrieve
+  the setting information from this file (that is, the &lt;server>
+  element with this ID value will be consulted for various
+  protocol-specific configuration values.)
+
+  <p>
+  See
+  <a href="http://maven.apache.org/plugins/maven-deploy-plugin/usage.html">the maven-deploy-plugin usage
+  page</a> for more details.

+<div>
+  If checked, the deployment will assign timestamp-based unique version number
+  to the deployed artifacts, when their versions end with <tt>-SNAPSHOT</tt>.
+
+  <p>
+  To the best of my knowledge, this is almost never a useful option especially
+  for CI servers like Hudson.
