Glcd contains a parser to enable getting information from the rest of the
system. The parser parses the text in some properties, eg the text property
of the text input module. A piece of text between round brackets is 
a piece of text to be parsed. (When you want literal round brackets in your
text, please escape them: '\(' & '\)' )
Those pieces of text are structured as follows
(method:arg1:arg2:arg3:...)
The methods are described in doc/parser/*.
In the arguments, please remember these chars have to be escaped by prepending 
them with a \: '\' '(' ')' ':'
