// $Log$
// Revision 1.5 2006/02/03 18:41:26 fraggle
// Support NWT-style WAD merging (-af and -as command line parameters).
// Restructure WAD loading so that merged WADs are always loaded before
// normal PWADs. Remove W_InitMultipleFiles().
//
// Revision 1.4 2005/10/08 18:22:46 fraggle
// Store the cache as part of the lumpinfo_t struct. Add W_AddFile prototype
// to header.
//
// Revision 1.3 2005/07/23 18:54:06 fraggle
// Use standard C functions for WAD code
//
// Revision 1.2 2005/07/23 16:44:57 fraggle
// Update copyright to GNU GPL
