.RE

.SH OPTIONS
.IP "-c" 10
Use this option to gather only cpuset information.  This is important
it is necessary to get information about a cpuset-aware system that is
not running as the PBS server/scheduler.
 
.IP "-d daterange" 10
Specifies a date range or a single integer representing the number of
days in the past to retrieve server and scheduler logs.  Date ranges
must be of the form MM/DD/YYYY-MM/DD/YYYY

.IP "-f" 10
Use this option for non-interactive mode.  The greeting will be
supressed, as will the command execution confirmation and prompts for
additional parameters.  If no other options are specified, only 
basic configuration information is collected.

Must use 
.I -u 
option with this option.

.IP "-g core_file"
Path to core file.
Obtains a stack trace from the specified core file produced by one of
the three PBS daemons.  Works only on Linux systems where gdb (the GNU
debugger) is installed.
 
If the -g option is specified, no other data collection will take
place.
 
.IP "-j jobidlist" 10
Collects information about specified job IDs.  Use this option on the
command line, to avoid being prompted during the running of the
script.  Format: comma-separated list of job IDs.
 
.IP "-o outdir" 10
This overrides $HOME as the default location for
the output .tar.gz file.
 
.LP

.IP "-n x"
.IP "-r remote_command"
.IP "-u username" 10
These options are used only during the pbs_dtj portion of the script
and map directly to the options in that script.  See the pbs_dtj
header for details.
 
The -u option must be specified for non-interactive use, i.e. when the 
.I -f
option is used..
