With Software Collections, you can build and concurrently install multiple versions of the same software components on your system. Software Collections have no impact on the system versions of the packages installed by any of the conventional RPM package management utilities.
== Example ==
Following [https://developerblog.redhat.com/2013/02/14/setting-up-django-and-python-2-7-on-red-hat-enterprise-6-the-easy-way/ this article], I installed Python 2.7 on an old RHEL 6.7 box.
<source lang="bash">
sudo sh -c 'wget -qO- http://people.redhat.com/bkabrda/scl_python27.repo >> /etc/yum.repos.d/scl.repo'
sudo yum install python27
scl enable python27 bash
python -V
</source>
For whatever reason, I wasn't getting a 'new' python in my bash shell, so I su'd to root where python 2.7 and 2.7.5 were available??
