    DESCRIPTION
        converts ascii files generated by SUFAR ver.4.0 to MagIC formated
        files for use with PmagPy plotting software

    OPTIONS
        -h: prints the help message and quits
        -f FILE: specify .asc input file name

        -Fa AFILE: specify rmag_anisotropy output file # MagIC 2 only
        -Fsi SFILE: specify specimens output file
        -usr USER: specify who made the measurements
        -loc LOC: specify location name for study
        -ins INST: specify instrument used
        -spc SPEC: specify number of characters to specify specimen from sample
        -ncn NCON:  specify naming convention: default is #2 below
        -k15 : specify static 15 position mode - default is spinning
        -new : replace all existing magic files

    DEFAULTS
        AFILE: rmag_anisotropy.txt  # MagIC 2 only

        SPEC: 0  sample name is same as site (if SPEC is 1, sample is all but last character)
        appends to  specimen/sample/site files
       Sample naming convention:
            [1] XXXXY: where XXXX is an arbitrary length site designation and Y
                is the single character sample designation.  e.g., TG001a is the
                first sample from site TG001.    [default]
            [2] XXXX-YY: YY sample from site XXXX (XXX, YY of arbitary length)
            [3] XXXX.YY: YY sample from site XXXX (XXX, YY of arbitary length)
            [4-Z] XXXX[YYY]:  YYY is sample designation with Z characters from site XXX
            [5] site name same as sample
            [6] site name entered in site_name column in the orient.txt format input file  -- NOT CURRENTLY SUPPORTED
            [7-Z] [XXXX]YYY:  XXXX is site designation with Z characters with sample name XXXXYYYY
