     The listed files (or _s_t_d_i_n, if none are given) are compressed using
the  Ziv-Lempel algorithm.  If the output is smaller than the input, the
output is put on _f_i_l_e._Z or _s_t_d_o_u_t if no files are listed. If _c_o_m_p_r_e_s_s is
linked  to  _u_n_c_o_m_p_r_e_s_s,  the  latter  is the same as giving the ---ddd flag.
Similarly, a link to _z_c_a_t decompresses to _s_t_d_o_u_t.  The MINIX version  of
_c_o_m_p_r_e_s_s  uses  13-bit  compression.   This  means that when compressing
files on other systems for transmission to MINIX, be sure that only  13-
bit  compression  is  used.  On many systems, the default is 16-bit (too
big).
