When modifying the smart font code, any changes required in the OpenType code should
be done first, and updated OpenType versions of the fonts should be built. Then the
revised Graphite code should be added. Thus:

1.  Start with the raw font (no smart font code) generated by FontLab or another 
    font editor.

2.  Add the OpenType code (as modified) to the font. See the README file in the
    "opentype" subfolder.

3.  Edit the Graphite files as needed.

4.  Run the graphite compiler. A typical command line would be:

    grcompiler -D -w3521 TaiHeritageMainR.gdl TaiHeritageProR-OT.ttf TaiHeritageProR_Graphite.ttf

        where:
            "TaiHeritageProR-OT.ttf" is the OpenType-enabled font produced in step 2, and
            "TaiHeritageProR_Graphite.ttf" will be the output font containing both OpenType
            and Graphite code.
    
    See the Graphite compiler documentation for more details.
