 The meta-grammar consists of global order constraints that provide succession of given terminals. Meta-grammar contains special flags that impose partial restrictions to given non-terminals and terminals on the right side of the rule.

+=== Arrow Types ===
 
 Different arrow marks (->, -->, ==>, ===>) are used in the grammar rules for specifying the rule type. The meaning of the arrows is as follows: "the thicker and longer the arrow the more actions are performed during rule translation":

 The grammar contains several generative constructs starting with %list_* expression. This construct defines rule templates which automatically produce new rules for a list of the given non-terminals.
 
+There are several functions:
+ * %list_coord - provides coordination on non-terminals
+ * %list_nocoord - provides no coordination on non-terminals
+ * %list_coord_case_number_gender - provides coordination of case, number and gender on non-terminals. The case, number and gender can be used respectively.
+ * %list_coord_propagate_plural - provides coordination on non-terminals and propagates plural. Can be used with case, number and gender.
