/** \ingroup python
* \name Class: Rpmspec
* \class Rpmspec
* \brief A python rpm.spec object represents an RPM spec file set.
*
* The spec file is at the heart of RPM's packaging building process. Similar
* in concept to a makefile, it contains information required by RPM to build
* the package, as well as instructions telling RPM how to build it. The spec
* file also dictates exactly what files are a part of the package, and where
* they should be installed.
*
* The rpm.spec object represents a parsed specfile to aid extraction of data.
*
* For example
* \code
* import rpm
* rpm.rpmPushMacro("_topdir","/path/to/topdir")
* s=rpm.spec("foo.spec")
* print s.prep()
* \endcode
*
* Macros set using add macro will be used allowing testing of conditional builds
*
