There's a README file for the installation. CoStLy has been implemented and tested on PCs with Linux. The current version of the library requires the GNU C++ compiler gcc 4.2.1 (or higher; earlier versions from 2.95.2 may also work) and the C-XSC interval library (Release 2.2.3 or higher). C-XSC is available at http://www.xsc.de.
