_D_e_s_c_r_i_p_t_i_o_n:

     Read the header information from a GenePix Results (GPR) file.
     This function is used internally by 'read.maimages' and is not
     usually called directly by users.

_U_s_a_g_e:

     readGPRHeaders(file)

_A_r_g_u_m_e_n_t_s:

    file: character string giving file name, including path if not in
          current working directory

_D_e_t_a_i_l_s:

     Output files produced by the image analysis software GenePix
     include a number of lines of header which contain information
     about the scanning process. This function extracts that
     information and locates the line where the intensity data begins.

_V_a_l_u_e:

     A list with components corresponds to lines of header information.
     All components are character vectors.
