	_D_e_s_c_r_i_p_t_i_o_n:
	
	     paste converts its arguments to character strings, and
	     concatenates them (separating them by the string given
	     by sep).  If a value is specified for collapse, the
	     values in the result are then concatenated into a sin-
	     gle string, with the elements being separated by the
	     value of collapse.
	
	     The concatenated value is returned as the value of
	     paste.
