Dumping a search tree
Are there any engines besides a special compile of Crafty (trace command) that will output a tree search to screen/disk?

The resulting file is a text file. In retrospect it would have been far more efficient to use a binary dumping format and then to use a utility to extract a human readable tree from it. Of course one is limited by disk space. The tree grows very rapidly.
