[s9;%% CParser is simple yet very useful lexical analyzer suitable 
for building descent parsers of languages with C`-like syntax.&]
[s9;%% CParser works on `'`\0`' terminated text in memory (not Stream), 
so to parse the file you have to load it into the memory first. 
Text has to exist during the time it is processed by CParser 
(no copy is made).&]
[s9;%% Many CParser methods can throw CParser`::Error exception to 
indicate the failure to parse required symbol. When using CParser 
to build concrete parser, it is common to use this exception 
(preferably via ThrowError method) to indicate errors as well.&]
