``--prefix`` injection takes place. You can also set the ``--prefix``
parameter explicitly in ``configure-options``.
``share``
``shared``
Specify the path in which this package is shared by many other
packages. When it's unset or blank, it means the package isn't
shared. Otherwise, it shared by many packages. Recipe will return
an empty list so that buildout will not uninstall the package when
uninstalling part.
In share mode, ``promises`` should be set so that recipe can tell
whether the package is installed. Otherwise nohting to do.
If ``share`` is not empty, ``location`` will be set to value of
``share``, and remove trailing '/'. So in case ``share`` is '/',
``location`` will be set to blank. Thus any reference like
"${part:location}/bin" in other parts will get the correct value.
This option is experiment now. Recipe doesn't try to set prefix
with the valule of this opton in the configure or make command,
you should specify them accordingly by yourself.
