[Rock-dev] autoproj v1.8.0 and autobuild v1.6.0 have been released !

[Sylvain Joyeux]

The major feature added to this new releases is parallel build across 
packages. If building with 8 jobs, one can now have 3 in a CMake package 
and 5 in another. autobuild plugs itself into GNU make's jobserver 
mechanism, so this balancing is dynamic. See NOTES FOR PACKAGE SET 
MAINTAINERS after the changelog for some important info.

CHANGELOG
---------
  * be compatible with Ruby 1.9.3
  * fixed minor issues when a package name is a substring of another
    (e.g. my/package and my/package_handler)


NOTES FOR PACKAGE SET MAINTAINERS
---------------------------------
Due to the extension of parallelism across packages, testing is needed 
for people that do some trickery in their autobuild files. In particular:
   - the use of Dir.chdir is forbidden in package handlers. Can be used
     in its block form (Dir.chdir { }) in the toplevel autobuild code,
     though. If you want to call a subcommand in another directory, use
     the new :working_directory option to Autobuild::Subprocess.run
   - progress reporting has significantly changed.
