Utilities

Here are some utilities you may find useful.

chklat.c is a small C program for verifying configs written in QCD archive format. It is meant to compile with the minimal (i.e. NULL) Makefile; just "make chklat" and your machine should produce an executable. This program parses the header, computes the checksum, checks for unitary links, and produces the average link trace and plaquette.
Source for the GNU utility wget-1.5.3. Just "wget URL" and the bytes which come back are stored on a file on your local computer. This a good method for grabbing configurations from machines without graphical browsers, or from inside scripts. On most workstations, building wget should be as easy as ". /configure" and "make". On the Cray systems some modifications are necessary.
For usage instructions, see wget notes
As a debugging aid, u_TEST_4223.101 is a small (4x2x2x3) configuration written in archive format, and u_TEST_4223.101.txt is the same data written in ASCII. This is a gauge transform of the trivial configuration, so every plaquette should be 1.0.
