Redcore Linux is a distribution based on Gentoo Linux and a continuation of the now-defunct Kogaion Linux.
Kogaion Linux itself was a distribution based initially on Sabayon Linux and later on Gentoo Linux.
Redcore Linux targets casual Laptop/Desktop users and, to some extent, Workstation power users.
It will nicely fill any gaming, multimedia, office, and internet browsing needs. Some development tools are also available.
For that reason, one cannot expect to find any server application in the repository (apache, Lighttpd, MySQL, Nginx, etc.). The repository will always remain small in size, focusing on quality and performance rather than quantity.
