+====== Building RPMs ======
+An RPM is a pre-compiled package containing binaries and config files, etc which can be installed using ''rpm'' or ''yum'' command line tools.  An SRPM or "source RPM" contains everything you need to rebuild a package.  Sometimes a binary RPM is not available, you can build a custom RPM using the SRPM file.

+Install ''rpmbuild'' (from the rpm-build package):
+<code>$ sudo yum install rpm-build</code>
+Setup your home directory's environment:
+<code>$ cp -a /usr/src/redhat/ ~/rpmbuild
+$ echo '%_topdir %(echo $HOME)/rpmbuild' > ~/.rpmmacros</code>
+Download an SRPM and build:
+<code>$ wget http://mirrors.geekymedia.com/centos/python26-2.6-geekymedia1.src.rpm
+$rpmbuild --rebuild EMBOSS-5.0.0-1.src.rpm</code>
+Install with:
+<code>$ sudo rpm -i ~/rpmbuild/RPMS/x86_64/python26-2.6-geekymedia1.x86_64.rpm</code>
+If upgrading, use
+<code>$ sudo rpm -U ~/rpmbuild/RPMS/x86_64/python26-2.6-geekymedia1.x86_64.rpm</code>
+====== Troubleshooting ======
+If you have problems with GPG errors, add a line like this to your ''~/.rpmmacros'':
