I agree with Massimo, the NOT packing facility could be handled by .hgignore.
As for configuration, I have used 0_config.py in blogitizor so that I can run two versions, my personal version and the one that is open source, this way my database and email information doesn't get leaked out into the internetz. I use the following, http://code.google.com/p/blogitizor/source/browse/src/models/A_config.example And then rename it to A_config.py and it won't get committed since src/models/A_config.py is placed in my .hgignore file. However this isn't a web2py mechanism just a personal one, I don't like the idea of making web2py in charge of this because then I the developer lose control and can't change the way it works without forking web2py. -- Thadeus On Fri, Jun 4, 2010 at 3:28 AM, Iceberg <iceb...@21cn.com> wrote: > Aside from the config issue, a flag when packaging that does not > package the database/ folder, would be the long missing piece.
