Usage: score pattern value
Usage: unscore pattern [ pattern ... ]
The score commands adds value to a message's score if pattern
matches it. pattern is a string in the format described in the
patterns section (note: For efficiency reasons, patterns
which scan information not available in the index, such as ~b,
~B or ~h, may not be used). value is a
positive or negative integer. A message's final score is the sum total of all
matching score entries. However, you may optionally prefix value with
an equal sign (=) to cause evaluation to stop at a particular entry if there is
a match. Negative final scores are rounded up to 0.
The unscore command removes score entries from the list. You must
specify the same pattern specified in the score command for it to be
removed. The pattern ``*'' is a special token which means to clear the list
of all score entries.
