+GROUP: Mail will be stored in GROUP (a string).
+
+\(FIELD VALUE SPLIT): If the message field FIELD (a regexp) contains

+\(| SPLIT...): Process each SPLIT expression until one of them matches.
+ A SPLIT expression is said to match if it will cause the mail
+ message to be stored in one or more groups.

+\(& SPLIT...): Process each SPLIT expression.

+FIELD must match a complete field name. VALUE must match a complete
+word according to the fundamental mode syntax table. You can use .*
+in the regexps to match partial field names or words.

+FIELD and VALUE can also be lisp symbols, in that case they are expanded
