Thanks Allan, this is a lot clearer now.
Just a couple more questions..

Would you expect it to be pure shell/bashscript, or could I use node/php
etc?
I know some bundles use ruby or node, but with CSS being a core bundle I'm
not sure if you try to reduce runtime dependencies?

Ok, I will output column offset anyway, and then TM can just ignore it

What are your thoughts when a line has more than one color....
border-color: #F00 #0F0 #00F #FF0;

I could either just output the first color and discard the rest
Or I could output them all, in reverse order (maybe for future use somehow?)
This would mean they are all included, but the first color ends up
overwriting the latter ones in the gutter.

Safe to just hardcode this path relative to ~/ ?
Or should I be basing it on some $TM_ENV_VAR ?

This seems like a good solution.
Should I namespace my 'colors' dir to include a bundle name subdir?

~/Library/Caches/com.macromates.textmate.colors/css/*.eps

Im thinking if another bundle was ever to use this gutter color api, my
bundle can call

--clear-mark ~/Library/Caches/com.macromates.textmate.colors/css/

and it would avoid clearing any color marks other bundles might have set?
Not sure, perhaps I'm overthinking it :-)

Thanks
