## Processing all a directory

The easiest MRTCAL session is:

    MRTCAL> index build      ! Build the index of IMB-FITS files in the current directory
    MRTCAL> mfind            ! Select all the files for calibration
    MRTCAL> mlist            ! Optionally list the files to be calibrated
    MRTCAL> file out myclassfile.30m single  ! Open a new Class output file
    MRTCAL> pipeline         ! Calibrate all the files

This calibrates all the IMB-FITS files present in the current directory. The command `MFIND` is used to build the current index from all the files in the input index. The command `PIPELINE` processes all, and only, the entries in the current index. It chooses automatically how the calibration and science scans are paired. As a result, the calibrated spectra are saved in the named CLASS file and the index is updated to reflect the calibration status of the IMB-FITS files.
