CodeReady

CodeReady is the name trademarked/protected by Red Hat (and they use it as repo name xDDD). For EL version 8 CentOS popularize the most popular name for this repository PowerTools.

More information:

**This used to be the case for EL8 and with EL9 the 'CodeReady' name appears to be replaced with 'CRB' (CodeReady Builder. The rebrander script changes this reference as well and leaves the initial one just for the sake of compatibility

just in case something changes in the future.**

Use following substitutions then use substitutions that are prestended above:

Red Hat CodeReady Linux Builder -> EuroLinux CRB
CodeReadyBuilder -> CRB
CodeReady-Builder -> CRB
CodeReady Builder -> CRB
CodeReady -> CRB
codeready-builder -> crb
codeready -> crb
