Hi Pavel,

I looked into Mirrors.1.cs and Bootstrap.st, how did you manage "mirrors  
are modified so they contain whole class hierarchy for new system. There  
are original classes used in code of methods."

Being aware that the answer most likely is "manually", could you post an  
"abstract" so that other people (especially me) can learn from your  
experience.

Thank you very much in advance.
