$ /usr/share/pvm3/bin/LINUXI386/tracer -h

usage:  tracer [ -T tracefile ] [ -O outfile ] [ full | time | count ] [ -Hhev ]

where:
------
-T file    = Use "file" as Trace File
-O file    = Use "file" as Additional Output File
-B nbytes          = Set Trace Buffer Size to nbytes
full       = Set Tracing Option to Full
time       = Set Tracing Option to Timing
count      = Set Tracing Option to Count
-H/h       = Print This Help Information
-e         = Dump Raw PVM Event Text
-v         = Verbose Operation

Comment 2 Doug Ledford 2008-06-19 18:15:54 UTC

This program isn't intended to be run by hand, and when run by pvm/xpvm, the
options are controlled so this isn't an issue.
