-Pl_mom is organized as two processes.  The reboot process runs every
-second, and the slice reset process runs every 30 seconds.  The reboot
-process is very lightweight and only reads /proc/swaps.  However, the
-slice reset process may pull data from the slicestat sensor on port
-3100, which can potentially take a long time (on the order of minutes
-if there are thousands of processes on the machine).

----------

-Rename the parent directory from pl_mom to pl_dod-0.2 (or whatever is
-the appropriate version number listed in the Makefile).  Then "make
-rpm" should do it.

 Notes
 ------
 
-The name of the daemon is "pl_mom" but the package name is pl_dod.
-The reason is that the daemon and package were both originally called
-pl_dod.  Yum (the package management tool currently in use) does
-not seem to honor the "Obsoletes:" tag in the .spec file.  Therefore
-it was not possible to automatically update the old pl_dod package
-with a new one called pl_mom, and so the package kept the old name.
