I’ve just discovered that Tyndale House have a technical blog. Among the many items of interest is the detail that you can download the Perseus code and data and run it on your own PC. This is the Perseus Hopper project, apparently. Naturally this would be far faster than using the main site. But… apparently you need to know what you’re doing with Java. Well, as a Java programmer, I suspect I’ll give it a go!
PS: I’ve just read that you can’t run it on Windows, as it generates file names that are illegal. How very, very odd.
