building rpm from tar.gz od bz2

[Michal Zeravik <michalz olomouc com>]

Hi to all,

I red in rpmbuild manual It's possible to build
binary package from tar archive.
All I need is to pass right arguments to ./configure script,
make and build rpm package.
Does exist any simple way to do it without spec file?
For example build rpm after make.
