# IMPORTANT NOTE: The rpm process assumes that ~/.rpmmacros contains
#                 the following:
#
#	%_topdir	/var/tmp/rpmbuild
#	%_tmppath	%{_topdir}/tmp
#	%_builddir	%{_topdir}/BUILD
#	%_rpmdir	%{_topdir}/RPMS
#	%_sourcedir     %{_topdir}/SOURCES
#	%_specdir	%{_topdir}/SPECS
#	%_srcrpmdir	%{_topdir}/SRPMS
#	%_buildroot	%{_topdir}/BUILDROOT
#	%_rpmfilename	%%{NAME}-%%{VERSION}-%%{RELEASE}.%%{ARCH}.rpm
#
# If you are signing the rpms, you also need:
#
#	%_signature	gpg
#	%_gpg_path	~/.gnupg
#	%_gpg_name	__YOUR_NAME_HERE__
#	%_gpgbin	/usr/bin/gpg

# IMPORTANT NOTE: Unless the package redhat-rpm-config is installed,
#	 	  the calc-debuginfo rpm will not be created.
#
# IMPORTANT NOTE: These packages are important for general
#		  rpm processing:
#
#	rpm
#	rpm-python
#	rpmlint
#	rpm-build
#	rpm-libs
#	redhat-rpm-config
