Offline Mode Design

* UPDATE: 18-April-2005

  We cannot take the approach outlined below of detecting which remote
  repositories are "really" offline, since offline mode is more of a behavior,

  <expressions>
    <expression>
      <syntax>settings.offline</syntax>
      <configuration>
        <![CDATA[
    <offline>true</offline>
    ]]></configuration>
      <description>
        <![CDATA[
      Flags the system as offline, to prevent accessing the network to resolve artifacts or execute plugins.

      NOTE: It's also possible to switch to offline mode on a per-build basis, using the '-o' command-line option.
