Changelog for Users
-------------------
* fixed bad generation of env.sh. The (very annoying) problem of having
a partial env.sh file generated should now be fixed for good.
* much improved progress output for heavily parallel builds
* autoproj update and aup properly update the configuration if given
the autoproj/ folder. I.e.,
autoproj update autoproj/
is equivalent to autoproj update-config
* experimental support for Windows
* experimental support for MacOSX. The osdep system is using MacPorts
* autoproj now validates that you are using always the same ruby
version. It avoids potential issues in cases where both ruby 1.9 and
1.8 are used on the same system
* fix some issue with auto-adding packages. Autoproj would always
auto-add package X if e.g. amake is used, which works fine in most
but not all cases.
* host of fixes related to ignore_packages. In general, this should
really work well now
* fix Autoproj.set_initial_env. The details of this forgotten feature
is going to be in a blog post.
* fixed supurious log/ directory created in new bootstrapped
installations

Changelog for package set developers
------------------------------------
* the osdep: keyword can be used to trigger recursive resolution. I.e.,
one can do the following to avoid repeating a complete osdep
definition:

nokogiri:
gem: nokogiri
osdep: libxslt-dev
libxslt-dev:
ubuntu: libxslt-dev
