22 | /* This program reads the ".xml" event definitions input files |
23 | and constructs structure for each event. |
24 | |
25 | The program uses a very simple tokenizer, called from a hand written |
26 | recursive descent parser to fill a data structure describing the events. |
27 | The result is a sequence of events definitions which refer to type |
28 | definitions. |
29 | |
30 | A table of named types is maintained to allow refering to types by name |
31 | when the same type is used at several places. Finally a sequence of |
32 | all types is maintained to facilitate the freeing of all type |
33 | information when the processing of an ".xml" file is finished. */ |
