Arbitrary numberof threads can be used, even numbers like 17 are acceptable.To completely disable this feature just remove "-DPTHREADS -pthreads"from flags in makefile.For Windows + Mingw32, get pthreads library here:http://sources.redhat.com/pthreads-win32/License-------This software is published under terms of MIT license.See COPYING for full text of license.Website-------Latest version can be obtained at http://wiki.fiction.cz/Pyrit
