I am a fan of Perforce and therefore have seen a couple of references to jam as a better make. I've poked around a bit and tried to find a concise comparison of jam vs. make but still don't understand the difference.

Now I am looking at starting a big project at work with either Jam or GNU make. I'd like to know if Jam is really that much better that I should promote it, and if it is I need a quick reasoning to explain why I chose it rather than make. The project is complex, but will only be running on SUN Solaris systems and is actually a hardware simulation (using Verilog, but with a bunch of perl and other scripts).

Any advice?
