There are some documentation errors:
- ''weight space \mu'' should be either ''\mu-weight space'' or ''weight
space of weight \mu''
- There is a B(\Lambda) where there should be a B(\lambda)
- Last sentence before input: ''Mor more...'' should be ''For more...''
- The fact that the reference is the second edition of Kac should be in
the reference and not in the paragraph
