It's exactly what it says on the tin: a library that implements an 
algorithm for finding a minimal line-based edit script between two input 
texts, along with the ability to turn that into a unified diff.

Go have a look at the source code, which contains inline documentation:
https://github.com/livecode/livecode/blob/develop/extensions/script-libraries/diff/diff.livecodescript

You could also have a look at the tests:
https://github.com/livecode/livecode/blob/develop/extensions/script-libraries/diff/test

Its development was sponsored by David Simpson.  Check out FMProMigrator. :)
