_D_e_s_c_r_i_p_t_i_o_n:

     Parses and checks the dependencies of a package against the
     currently installed version of R (and other packages).

_U_s_a_g_e:

     package.dependencies(x, check = FALSE,
                          depLevel = c("Depends", "Imports", "Suggests"))

_A_r_g_u_m_e_n_t_s:

       x: A matrix of package descriptions as returned by
          'available.packages'.

   check: If 'TRUE', return logical vector of check results. If
          'FALSE', return parsed list of dependencies.

depLevel: Whether to look for 'Depends' or 'Suggests' level
          dependencies.

_D_e_t_a_i_l_s:

     Currently we only check if the package conforms with the currently
     running version of R.  In the future we might add checks for 
     inter-package dependencies.

_S_e_e _A_l_s_o:
