Here's some sample output from the attached script:

What's the syntax for importing these into an LLDB session?

It's:

script import {path to WebKit root}/Tools/lldb/lldb_webkit.py

Oh, and FYI, LLDB apparently hates the tilde, so you'll have to put the entire path in.

You can have the script automatically imported into lldb (and Xcode!) by adding the following to your ~/.lldbinit file:

command script import {path to WebKit root}/Tools/lldb/lldb_webkit.py
