From LQWiki

Core is a very stripped-down version of Linux that allows you to build a system from scratch. You boot from the CD, install the necessary infrastructure, and build the kernel.

Summary

Directly from their site:

Core is a minimal distribution of the GNU/Linux operating system designed to be the basis for a complete system constructed by the end user. A fresh installation of Core will boot into a console and provide the user with the tools needed to download, compile and install other applications. Core contains nothing beyond what is required to perform these tasks.

Core is primarily designed for experienced Linux users, though it has found an audience with those looking to learn about the internals and operation of a Linux system. Core requires the user to manually configure, compile and install applications and expects the user to consult man pages and other documentation.
