Re: Working on a Debugger for Gjs

[Sam Spilsbury <smspillaz gmail com>]

Hi all,

Just by way of follow up, I've submitted the first set of patches
here[3]. Please feel free to try and break it - I need to know whether
or not I've got the overarching design right before I start adding any
more new features.

Cheers,

Sam.
