[NTG-context] Place for exercises and solutions

[batela]

Dear Sirs,

I'm writing a chemical book and I want include some exercises in the 
end of each chapter. In the source file the solutions are placed after 
the related exercise. In the .pdf file the exercises should be located 
at end of each chapter, but the solutions should appear in the end of 
the book.

Did anybody has a similar implementation?


Thanks a lot
