 /*
  * opiealarm.c
  *
  *  This program is for extracting the event time/date out
- *  of /etc/resumeat and setting the RTC alarm to that time/date.
+ *  of /var/run/resumeat and setting the RTC alarm to that time/date.
  *  It is designed to run via a script just before the iPAQ
  *  is suspended and right after the iPAQ resumes operation.
