About Software Collections
--------------------------
Software Collections give you the power to build, install, and use
multiple versions of software on the same system, without affecting
system-wide installed packages. Each collection is delivered as a group
of RPMs, with the grouping being done using the name of the collection
as a prefix of all packages that are part of the software collection.

The SCLo SIG in CentOS
----------------------
The Software Collections SIG group is an open community group
co-ordinating the development of the SCL technology, and helping curate
a reference set of collections. In addition to the collection MariaDB
being released here, we also build and deliver databases, web servers,
and language stacks including multiple versions of PostgreSQL, MongoDB,
Apache HTTP Server, NodeJS, Python and others.

You can learn more about Software Collections concepts at:
http://softwarecollections.org
You can find information on the SIG at
https://wiki.centos.org/SpecialInterestGroup/SCLo ; this includes howto
get involved and help with the effort.
