#Tokeniser rule file
#Each rule should be on one line
#Lines that end with "\" are appended with the next one. This facility \
 is used for longer rules that cannot be written on a single line
#
#Lines starting with "#" are treated as comment
//Lines starting with "//" are treated as comment
# Empty lines are ignored.

#A rule has a left hand side (LHS) and a right hand side (RHS);
#the RHS is a regular expression tha has to be matched on the input
#the LHS describes the annotations to be added to the AnnotationSet.
#LHS is separated from the RHS by '>'
#LHS knows about the following operators:
#	+ (1..n)
#	* (0..n)
#	| (boolean OR)
#
#RHS uses as separator ';' and has the following format
#{LHS} > {Annotation type};{attribute1}={value1};...;{attribute n}={value n}


#The primitive constructs are:
#UNASSIGNED
#UPPERCASE_LETTER
#LOWERCASE_LETTER
#TITLECASE_LETTER

#NON_SPACING_MARK
