iang: dikau jalaninnya gmn? Syntax reference:

"ptb Permutation.dll Permutation"

means: test run class Permutation from assembly Permutation.dll

Cobain pake Reflector (Win only), dibuka reference DLLnya. Di situ keliatan semua gimana cara mulai bikinnya. Ini emang ngga secara eksplisit gw buka, kalian udah ngerti apa itu reverse engineering kan? :D
