24 # FIXME: |
| 3999 | 25 # |
| 26 # * Improve default documentation and/or individual documentation | |
| 12254 | 27 # in data files. |
| 3999 | 28 # |
| 29 # * Fix print/show code to display/return something more informative | |
| 30 # for special values (for example, -1 ==> infinite in some cases). | |
| 31 # Probably need more information in the data files for this. | |
| 32 | |

| 34 # | |
| 35 # CLASS = string | |
| 36 # FCN_NAME = string | |
| 4044 | 37 # INCLUDE = file |
| 3998 | 38 # DOC_STRING doc END_DOC_STRING |
| 39 # OPTION | |
| 40 # NAME = string | |
| 4050 | 41 # DOC_ITEM doc END_DOC_ITEM |
| 3998 | 42 # TYPE = string |
| 43 # SET_ARG_TYPE = string (optional, defaults to TYPE) | |
| 44 # INIT_VALUE = string | INIT_BODY code END_INIT_BODY | |
