DESCRIPTION
In software, stability and freshness are often at odds. Sometimes you want to have a known environment with a fresh piece or two of software. Amazon Linux provides fresh software on an optional basis, which you can fetch with this tool. You can specify a version of a topic by appending to its name, an equal-sign and then the version string, in the style of topic=ver . Specifying a version is a good idea if you wish to have reproducible environments. If you do not specify a version, you will use the symbolic name "latest", which always refers to the most recent version, floating over time. That is, your software retrieval system will point to the ever-changing contemporaneous "latest", not to a point in time frozen at when you enable that topic. Future updates will fetch things that have changed. Though it exists as an option here for advanced usage, disabling software after it is installed is not recommended or supported.

CONFLICTS
Not all software topics are compatible. Repositories that provide different versions of the same software probably cannot cohabitate, and so by enabling one you probably make the other impossible to enable.
