All built into modern scripting languages. Only in C you have to reinvent
it.

The main use case is really custom analysis, so that people can do
whatever custom data mining they want.

But I expect once you get users engaged with a simple interface
you'll get much more.

But even the existing script is quite useful and gives you
a lot of information. It's also very easy to extend to everyone
knowing SQLite.

Can you do all these things the simple script does?
