- * MODULE: iostream
- *
- * COPYRIGHT (C) 2007 Laura Toma
- *
- *
- * Iostream is a library that implements streams, external memory
- * sorting on streams, and an external memory priority queue on
- * streams. These are the fundamental components used in external
- * memory algorithms.
- * Credits: The library was developed by Laura Toma. The kernel of
- * class STREAM is based on the similar class existent in the GPL TPIE
- * project developed at Duke University. The sorting and priority
- * queue have been developed by Laura Toma based on communications
- * with Rajiv Wickremesinghe. The library was developed as part of
- * porting Terraflow to GRASS in 2001. PEARL upgrades in 2003 by
- * Rajiv Wickremesinghe as part of the Terracost project.
