      This is the preliminary version of the reference manual for the
      language ${\cal LL}$ designed for easy interfacing with complex libraries
      and testing of algorithms written in a natural way, avoiding
      complexities of typical system programming languages.  Generality
      is achieved through the fact that the language is completely
      object-oriented.  It provides traditional syntax and extended
      semantics for its declarations, statements and expressions.  Some
      of the most common data types and data structuring mechanisms are
      provided within the language, but it is expected that most of them
      will be defined through application oriented interfaces.
