/*
 * USAGE
 *
 *   delblk <database> <file>
 *
 * where <file> contains a list of YMDHMS profile times to delete from the
 * database. A log file delblk.log is created/appended with all profiles being 
 * deleted. If a given profile time is within 1 second of the real profile
 * time from the database, the profile is deleted. Otherwise, the profile is
 * skipped.
 *
 * I would like to provide an option for undeleting profiles.
