Good post !

From

http://www.shelldorado.com/goodcoding/cmdargs.html

the following explanation on the use of --

Code:
If you for example had a file named "-f", it could not be removed using
the command "rm -f", because "-f" is a valid command line option. Instead you
can use "rm -- -f". The double dash "--" means "end of command line flags", and
the following "-f" is then interpreted as a file name.

NAME
WMGRABIMGAE - Dockable WWW Image monitor. SYNOPSIS
wmGrabImage [-h] [-display <Display>] -url <Image URL> [-http <URL>] [-c] [-delay <Time>] DESCRIPTION
wmGrabImage is a WindowMaker DockApp that maintains a small thumbnail copy of your favorite image from the WWW. The image to monitor is specified via the "-url <Image URL>" command-line option and it gets updated approximately every 5 minutes. The update interval can be overridden via the "-delay <Time>" command-line option (Time is in seconds). Each of the three mouse buttons can be double clicked with the following effects; Left Mouse: Brings up the full-sized image in xv. Middle Mouse: Sends a URL (specified via the -http <URL> command-line option) to an already running netscape process or in a new netscape process if there arent any running. Right Mouse: Updates the image immediately. OPTIONS
-h Display list of command-line options. -display [display] Use an alternate X Display. -url <Image URL> The URL of the WWW image to monitor. -http <URL> The URL to send to netscape via a Middle double click. -c Center the image vertically within the icon. -delay <Time> The time between updates. The default is about 5 minutes. FILES
The original sized image and the thumbnail XPM image are both stored in ~/.wmGrabImage/ which gets created if it doesnt already exist. SEE ALSO
wget and the ImageMagick convert utility. BUGS
Who knows? -- its still Beta though. (Let me know if you find any). Oldish versions of the ImageMagick convert utility have a memory leak -- if you have that problem, upgrade to the latest version. AUTHOR
