- // The rules of organizing data in this file!
- //
- // 1. Begin each measure category with a line containing its name only.
- // 2. The next line contains the phrase of BEGIN only.
- // 3. The following lines begin with a Unit Name, Type, Symbol! and
- // Value. The Value in those lines stands for different meaning!
- // in the first line, it is always 1. The Unit Names below it are
- // the multiplication factor to obtain 1 of the first Unit Name.
- // 4. The next line contains the phrase of END indicating the
- // category has ended.
- // 5. Any blank lines are not counted as a line no matter how many
- // empty lines areincluded in the text.
- // 6. Begin any comment line with double forward slashes.
- // 7. Measure units in a categoty should be arranged alphabetically.
- // 7. For ease reading or editing, it is better to arrange measure
- // units in a category alphabetically.
- // 8. For ease reading or editing, it is better to arrange categories
- // alphabetically.
