Building Grendel: Make sure you have the required (external) packages first. Then edit the top-level rules.mk file, setting the CLASSPATH and other variables appropriately for your system. Remember to add two dirs to your classpath for grendel: the your/path/mozilla/grendel dir itself *and* the your/path/mozilla/ dir. Then run 'make' in your grendel dir. All files should build fine. Running Grendel: There are currently two ways you can run Grendel: 1. Type 'java grendel.Main' (with the correct CLASSPATH of course) 2. Type 'make run' after building and watch it work.
