I configured invoking a program when an incoming message has been received.  Per the documentation, I expected that I could display the notification using osd_cat.  I found that the notification contains tags which I needed to strip with the following command:

awk '/[<]qt[>].*[<]br[>]/ { print gensub(/[<]qt[>](.*)[<]br[>].*/, "\\1", "g") }'

I am only interested in who sent me a message, not the message itself.  Perhaps having a formatting string (e.g. %w) that expand into who sent the message a formatting string (e.g. %m) that expands into the message.
