WYSIWIG conditional compilation preprocessor for Java etc.
...The principal objection to a preprocessor is that it makes one's code difficult to read. This is indeed true for the C preprocessor. It is sometimes difficult to determine which lines of code are active and which are not. Being WYSIWYG, the PreprocessorWizard multi-language WYSIWIG preprocessor resolves the problem of code being difficult to read and allows one preprocessing syntax for all languages. It is easy to use as a standalone application and it can be easily integrated with almost any IDE.
