[texworks] Simple examples of TeXWorks scripts?

[Duncan Murdoch]

I didn't get a reply to my specific question about triggering a refresh 
of the PDF view, so I guess I'll have to write it myself.  Could someone 
point me to documentation and simple examples of scripting TeXWorks?

Things I'd like to do:

  - process options on the command line

  - open a particular PDF, or refresh the display if it is already open

Thanks in advance for any suggestions.
