	Change:
if "$1" contains "a" then set visible of every process whose visible 
is true and name is not "Finder" and name is not "$2" to false
	to:
if "$1" contains "a" then set visible of every process whose visible 
is true and name is not "Finder" ${2+and name is not \"$2\"} to false
	Do similar to '-o' line
	and change:
if "$1" contains "v" then tell me to tell application "$2" to activate
	to:
${2+if \"$1\" contains \"v\" then tell me to tell application \"$2\" 
to activate}

$var is replaced by the value of var
${var+some text} is replaced by nothing at all if var is unset, or by 
'some text' if var has a value
Here, the text introducing the use of the 2nd parameter is only 
included if the 2nd parameter is given.
See the man page for full details.  There is also ${var-}, ${var=} 
and ${var?} and more.

This 'here is' approach will only work with applications that have 
single word names.  '$*' would include the flags, so they need to be 
captured and shifted off first.  My solution at
<http://homepage.mac.com/david_ledger/Scripts/index.html>
gets round this.  You probably won't like my multi-char flags, but 
those can be changed to something that makes sense to you.

I do still get the error:
## Component Manager: attempting to find symbols in a component alias 
of type (regR/carP/x!bt)
but I get that in other places too.  Any ideas?
