title: How to set defaults for perforce client specs
body: <p>I'm trying to discover how to change the default set of Client Spec options and submit-options.</p>
  
  <pre><code>set P4CLIENT=my_new_client_1
  p4 client
  </code></pre>
  
  <p>Gives me the following spec default-spec:</p>
  
  <pre><code>Client: my_new_client_1
  ...
  Options:    noallwrite noclobber nocompress unlocked nomodtime normdir
  
  SubmitOptions:  submitunchanged
  ...
  </code></pre>
  
  <p>Now on my machine i want to always use <code>revertunchanged</code>, <code>rmdir</code> for example, but it seems like I need remember to manually set this everytime I create a new client.</p>
  
  <p>Is there any way to achieve this?  p4 set seems to only affect the things that can be set by environment variables.</p>
