During the review process for openclonk[1] it was discovered that it had a bundled copy of sort.h. It's unusual as it is not designed to be built into a stand alone library, static or shared. In fact it does not contain a make file. - It's not already packaged in Fedora or RPM Fusion - It's a header only library (essentially a copylib) If the consensus is to allow the exception, my plan is to do the following: - add a virtual provides for tracking purposes: Provides: bundled(timsort) - Add a "Provides: bundled(timsort)" with version per the Fedora guidelines.
