I'm trying to make a new gtk theme using the murrine engine, using Humanity (default in ubuntu 9.10) as a template.
You can grab the code in http://github.com/tutuca/themes
However, I found cumbersome the process of creating a new theme with it. There is no central starting point.
The documentation of both, the engine options (gtkrc's and stuff), and general theming practices (the format of the index.theme files, folders, bla bla) is scarce, How to's and tutorials are often old or subject to lots of opinionated debate and results confusing (to me, having a web developer background, at least :-).
So... I wanted to ask to the fellows gtk themers and artist out there:
Which tools you use to create a new theme, and how does your average workflow looks like?
