This software is a translation into C++ of the excellent Webgraph library by P. Boldi and S. Vigna. The original library, written in Java, is easy to use but hampered by some requirements of the Java virtual machine. This C++ translation attempts to preserve much of the ease of use (through integration with the Boost Graph Library), but bypass requirements imposed by a virtual machine.
