_D_e_s_c_r_i_p_t_i_o_n:

     This function is a low-level interface to the GNU Linear
     Programming Kit (GLPK) function 'lpx_read_cpxlp'.  The parameter
     names, associated types, and return values are identical to the
     GLPK function.  Please see the GLPK documentation for more info.

_U_s_a_g_e:

         lpx_read_cpxlp(fname)

_A_r_g_u_m_e_n_t_s:

   fname: see GLPK doc 

_D_e_t_a_i_l_s:

     This function is the interface to the R-glpk C function 
     'R_lpx_read_cpxlp' which converts R objects and  calls GLPK
     'lpx_read_cpxlp'.

_V_a_l_u_e:

     Returns  an external pointer object.   This pointer is opaque but
     is of type 'LPX *'. It can be used in related GLPK methods.  Any
     allocated memory associated with this pointer is handled by the R
     garbage collector. However, you may also call the GLPK destructor
     method of this class to free the memory and nullify the pointer.

_N_o_t_e:

     The generation of this function code, documentation, and R-API
     code has largely been automated.  Therefore, not all functions
     have been fully tested.  Beware and please report any bugs or
     inconsistencies.

     The full documentation for GLPK has not been converted to Rd
     format - it is available in the GLPK source distribution. 

     Inquiries regarding this interface (R-GLPK) should NOT be sent to
     GNU GLPK mailing lists.
