.SH DESCRIPTION
.B par
takes a list of files to run a command on.  The first line of each file begins
with a colon (:) or a pound-sign (#).  If a colon, the remainder of the
line is a command to run for each of the subsequent lines.  If a pound-sign,
then each subsequent line is a (self-contained) command, unless the 
.B \-c
option was specified, in which case it operates as if the argument to
.B \-c
had followed a colon on the first line.
.PP
In each of the cases where the lines of the file following the first are
not commands (i.e.: colon or -c), instances of open-close braces ({}) in the
command will be replaced by these values.
.PP
For example, a inputfile whose contents is:
.sp
	: echo {}
.br
	a
.br
	b
.br
	c
.sp
run with
.B par
like so:
.sp
	%par -q inputfile
.sp
will produce the following output (order will vary):
.sp
	b
.br
	a
.br
	c
.PP
The command-line options are as follows:
.\"
.TP
.B \-i
Run commands interactively through (multiple) 
.BR xterm (1)
processes.
.\"
.TP
.B \-l
Prefix of logfile name, as in prefix.N where N is the
.B par
process number ([0..]).
.sp
Default: par.log.<time>.[0..]
.\"
.TP
.B \-n
Number of simultaneous processes.
.sp
Default: 3
.\"
.TP
.B \-q
Quiet mode.  Do not log anything.
.B \-q
is mutually exclusive with the
.B \-x
and
.B \-l
options and the option appearing last will take precedence.
.\"
.TP
.B \-x
View par logs in real-time via an 
.BR xterm (1).
