Usage: pen_width [options] file1 [file2]
 
	pen_width changes the pen_width of a HPGL2 file by a factor 0.5
 
	options:	-h =>	this help screen 
			-o =>	output sed commands (don't change file)

	if only one file is given the old file will be overwritten.

	BUGS:	I wanted to be able to give the factor also as a commandline
		parameter, but haven't been able to do this. If you want a
		different parameter then you will have to change this script or
		run it several times (See the long command starting with cat
		to change the factor).

# 04-07-94 first version
#
# This scripts can change all the pen-widths in a HPGL2 file. It will
# multiply all the pen-widths by a certain factor.
#
# The script was created to be able to print large formats on a laserjet
# printer and still being able to read the text on the plot and see small
# details.
