_D_e_s_c_r_i_p_t_i_o_n:

     `autoload' creates a promise-to-evaluate `autoloader' and stores
     it with name `name' in `.AutoloadEnv' environment.  When R
     attempts to evaluate `name', `autoloader' is run, the package is
     loaded and `name' is re-evaluated in the new package's
     environment.  The result is that R behaves as if `file' was loaded
     but it does not occupy memory.
