%% @doc Rebuilds the specified WorkSpaces.
%%
%% Rebuilding a WorkSpace is a potentially destructive action that can result
%% in the loss of data. Rebuilding a WorkSpace causes the following to occur:
%%
%% <ul> <li>The system is restored to the image of the bundle that the
%% WorkSpace is created from. Any applications that have been installed, or
%% system settings that have been made since the WorkSpace was created will
%% be lost.</li> <li>The data drive (D drive) is re-created from the last
%% automatic snapshot taken of the data drive. The current contents of the
%% data drive are overwritten. Automatic snapshots of the data drive are
%% taken every 12 hours, so the snapshot can be as much as 12 hours old.</li>
%% </ul> To be able to rebuild a WorkSpace, the WorkSpace must have a
%% <b>State</b> of <code>AVAILABLE</code> or <code>ERROR</code>.
%%
%% <note> This operation is asynchronous and will return before the
%% WorkSpaces have been completely rebuilt.

%% @doc Terminates the specified WorkSpaces.
%%
%% Terminating a WorkSpace is a permanent action and cannot be undone. The
%% user's data is not maintained and will be destroyed. If you need to
%% archive any user data, contact Amazon Web Services before terminating the
%% WorkSpace.
%%
%% You can terminate a WorkSpace that is in any state except
%% <code>SUSPENDED</code>.
%%
%% <note> This operation is asynchronous and will return before the
%% WorkSpaces have been completely terminated.
