"Split rule for the command `elmo-split'.
The format of this variable is a list of RULEs which has form like:
-\(CONDITION FOLDER [continue]\)
+\(CONDITION ACTION [continue]\)
The 1st element CONDITION is a sexp which consists of following.
-1. Functions which accept argument FIELD-NAME and VALUE.
+1. Functions which accept arguments FIELD-NAME and VALUE.
FIELD-NAME is a symbol of the field name.
`equal' ... True if the field value equals to VALUE.
VALUE can contain \\& and \\N which will substitute
from matching \\(\\) patterns in the previous VALUE.
-2. Functions which accept any number of arguments.
+2. Functions which accept an argument SIZE, SIZE is some number.
+
+`<' ... True if the size of the message is less than SIZE.
+`>' ... True if the size of the message is greater than SIZE.
+
+3. Functions which accept any number of arguments.
`or' ... True if one of the argument returns true.
`and' ... True if all of the arguments return true.
-3. A symbol.
+4. A symbol.
When a symbol is specified, it is evaluated.
-The 2nd element FOLDER is the name of the folder to split messages into.
+The 2nd element ACTION is the name of the destination folder or some symbol.
+If CONDITION is satisfied, the message is splitted according to this value.
+
+If ACTION is a string, it will be considered as the name of destination folder.
+Symbol `delete' means that the substance of the message will be removed. On the
+other hand, symbol `noop' is used to do nothing and keep the substance of the
+message as it is. Or, if some function is specified, it will be called.
When the 3rd element `continue' is specified as symbol, evaluating rules is
not stopped even when the condition is satisfied.
