USAGE:

0. Make sure the real xst executable is in you PATH
1. Copy xstcache.py and xstcache_stats.sh to a directory of your choice (say /usr/local/xstcache)
2. Create a symbolic link to 'xst': cd /usr/local/xstcache ln -s xstcache.py xst
3. Prepend /usr/local/xstcache to your PATH: export PATH/usr/local/xstcache:$PATH # for bash
4. Run your EDK toolchain aus usual, e.g.: cd $MY_EDK_PROJECT make -f system.make netlist

The actual cache is stored by default in $HOME/.xstcache If something goes wrong or you want to start over, just delete that directory.
