  @brief Export format definitions
  @details Formats are exported from the first (if any) catalog entry in the
  FMTSEARCH path.
 
  Formats are taken from the library / dataset reference and / or a static
  format list.
 
  Example usage:
 
      %mp_getformats(lib=sashelp,ds=prdsale,outsummary=work.dictable)
 
  @param [in] lib= (0) The libref for which to return formats.
  @todo Enable exporting of formats for an entire library
  @param [in] ds= (0) The dataset from which to obtain format definitions
  @param [in] fmtlist= (0) A list of additional format names
  @param [out] outsummary= (work.mp_getformats_summary) Output dataset
    containing summary definitions - structure taken from dictionary.formats as
    follows:
 
  |libname:$8.|memname:$32.|path:$1024.|objname:$32.|fmtname:$32.|fmttype:$1.|source:$1.|minw:best.|mind:best.|maxw:best.|maxd:best.|defw:best.|defd:best.|

  @param [out] outdetail= (0) Provide an output dataset in which to export all
    the custom format definitions (from proc format CNTLOUT).  Definitions:
