The following script is entirely my own, for better or for worse. It is a self-contained script that calculates the set class of a given set. Given a particular set of pcs (numbers) in a given mod, the program returns the Tn and TnI classes, and the interval vector. The program is quite powerful, in that it handles decimals, negative numbers and multisets.

To install the script, go to Terminal (in mac), and find the directory where the script is located (using cd). If you need help with that, here is a page outlining some of the basic unix commands.

The script produces an index page equipped with an upload button, making it very handy for quick file-sharing via http.

To install, use the same method as given here. Once installed, use the script by doing:

This is really helpful for making sweeping changes among a collection of files, without having to edit each file individually.

There are two ways to use the script: with or without a file extension to limit the search. If no file extension is given, all files will be considered. Assuming the script is called ‘frpl’, here is the usage:
