    <flag name="doc">
      Rebuild the user documentation provided with the package; this
      should really not be necessary as all the documentation is
      shipped pre-built.
    </flag>

    <flag name="debug" restrict="&lt;fcron-3.0.5">
      Enable debug code, output and allocation checks. Warning: in
      ebuilds before 3.0.5, enabling this flag will prevent fcron from
      running as a proper service.
    </flag>

    <flag name="debug" restrict="&gt;=fcron-3.0.5">
      Enable debug code and output. Since version 3.0.5 this will no
      longer force foreground execution, and fcron will be able to run
      as a service properly.
    </flag>

    <flag name="pam">
      Enable PAM support for fcron. This means that fcron will pass
      through the “fcron” stack before executing the jobs, and
      fcrontab will use the “fcrontab” stack to authenticate the user
      before editing its crontab file.
