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

     This function handles the construction of xcmsSet objects. It
     finds peaks in batch mode and pre-sorts files from subdirectories
     into different classes suitable for grouping.

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

     xcmsSet(files = NULL, snames = NULL, sclass = NULL,
             profmethod = "bin", profparam = list(), ...)

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

   files: path names of the NetCDF/mzXML files to read

  snames: sample names

  sclass: sample classes

profmethod: method to use for profile generation

profparam: parameters to use for profile generation

     ...: further arguments to the 'findPeaks' method of the 'xcmsRaw'
          class 

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

     The default values of the 'files', 'snames', and 'sclass'
     arguments cause the function to recursively search for readable
     files. The filename without extention is used for the sample name.
     The subdirectory path is used for the sample class.

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

     A 'xcmsSet' object.

_A_u_t_h_o_r(_s):
