Description:
Kimwitu++ is the successor to Kimwitu. Like Kimwitu, it is a tool for 
processing trees (i.e. terms). It is a meta tool: Kimwitu++ can be used for 
generating software - especially when building compilers. Kimwitu++ has its own 
input language, which allows the definition fo the tree structure and of 
functions operating on the tree. It uses the input to generate a number of C++ 
files, which are then bound to a program using the C++ compiler.

Kimwitu++ can be easily combined with parser generators like lex and yacc. 
While the parser deals with processing the grammar rules, kimwitu++ deals with 
creating an abstract syntax tree. In further passes, this tree can be used to 
generate target code. These passes can be implemented in the same program or a 
different one - kimwitu++ supports saving the tree into files.

For processing the tree, Kimwitu++ supports two mechanisms: unparse rules (for 
code generation), and rewrite rules (for transformations). Each rule can be 
tailored to a specific node structure using pattern matching; all rules 
together are applied to the tree recursively. To support different rules for 
the same kind of node (in different application contexts), Kimwitu++ supports 
the definition of views.

Inside the rules, Kimwitu++ allows to integrate C++ code; it also provides some 
extensions to C++. For each node type, a class is generated, which can be 
extended with user-defined methods.
