no one? i'm still interested in a solution for this 
I don't really get the first part: "deliver some default makefile targets".
I guess what you should do in this case is to write a wizard that sets up a project as desired for you.
For the second part:
The tools menu is a per-user item. Although you can use e.g.
cb_share_config to exchange tool settings between installations that's probably no good and error prone, too (imagine you might overwrite tools a dev has created himselves...). Merging on XML file level (the settings file "
default.conf" is a XML file) is another idea but also no good (IMHO).
My strong suggestion is (if you you just want to add some tools): write a tiny plugin that creates an extra menu and triggers actions accordingly. This should be very easy to implement (we have a type "tools plugin" for such purposes). This way you would only need to distribute the plugin to your devs and the setup is equal to everyone.
