I'd like to debug a website that is using NACL, however the only way to access the site is through the NACL start page (see the picture below).
From this page, there is no way to access the developer tools and hence the debugger.
Is there a way to enable the Chrome debugger on a NACL website?

nacl-gdb is the tool for debugging -- single stepping instructions, inspecting memory, etc, like a normal native-code debugger.
