22 /* This program reads the ".xml" event definitions input files
23 and constructs structure for each event.
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
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. */
