Using things that are only supported on some platforms

[Bill Vlahos]

I have an application that uses revSpeak which works fine on Macs and  
Windows as it should. This command isn't supported on Linux but I  
thought I would try to see what happened if I tried anyway. I get an  
error "can't find handler".

Is this the expected behavior for a command that isn't supported?

I could either trap for platform or put the command in a try...  
statement.

Any thoughts?
