Yap, pasting the content of your former email (just rereading, see

My first search was unsuccessful, that's why I asked. But Gemfile seem
to be a good keyword so could retrieve the mail again, thx.

Because I find it to be a robust, self sufficient and transparent
process to start my installations.
All tools are (most often) onboard and no need to look for an
(potentially outdated) autoproj_install script.

I assumed eval_gemfile '.autoproj/Gemfile' etc. to be some kind of
redirection and would have expected: BUNDLE_GEMFILE=.autoproj/Gemfile.lock

But since 'eval_gemfile' is Bundler DSL and with your hint to
autoproj/Gemfile, I guess that this rather collects and injects all gem
dependencies for bundler?
