Tea Strainer

What is it?

Tea Strainer is a small utility script to debug the messages being passed to and from Teacup.

How Does it Work?

By intercepting the link message traffic in the prim Teacup resides in, it checks for messages that Teacup and it's components are passing back and forth to and outputs them as llOwnerSay messages. All currently known protocols are properly parsed, and unknown messages are labeled and output in condensed format as well.

//-- optimized for speed, NOT size
