Feature Changes

---------------

- A new command-line argument, -U, suppresses reading user defaults.

- You can now suppress use of an installed-part database
  (e.g. .installed.cfg) by sprifying an empty value for the buildout
  installed option.

Controlling the installation database
-------------------------------------
The buildout installed uption is used to specify the file used to save
information on installed parts. This option is initialized to
".installed.cfg", but it can be overridded in the configuration file
or on the command line:
>>> os.remove('.installed.cfg')
>>> print system(buildout+' buildout:installed=inst.cfg'),
>>> ls(sample_buildout)
- b1.cfg
- b2.cfg
- base.cfg
d bin
- buildout.cfg
d develop-eggs
d eggs
- inst.cfg
d parts
d recipes
The installation database can be disabled by supplying an empty
buildout installed opttion:
>>> os.remove('inst.cfg')
>>> print system(buildout+' buildout:installed='),
>>> ls(sample_buildout)
- b1.cfg
- b2.cfg
- base.cfg
