 /**
  * Run pull commands on local working copies to keep them up to date. This
  * daemon handles all repository types.
  *
  * By default, the daemon pulls **every** repository. If you want it to be
  * responsible for only some repositories, you can launch it with a list of
- * PHIDs or callsigns:
+ * repositories:
  *
  *   ./phd launch repositorypulllocal -- X Q Z
  *
  * You can also launch a daemon which is responsible for all //but// one or
  * more repositories:
  *
  *   ./phd launch repositorypulllocal -- --not A --not B
  *
  * If you have a very large number of repositories and some aren't being pulled
  * as frequently as you'd like, you can either change the pull frequency of
  * the less-important repositories to a larger number (so the daemon will skip
  * them more often) or launch one daemon for all the less-important repositories
  * and one for the more important repositories (or one for each more important
  * repository).
