Suggestion: define who your target user is. A dev who speaks one lang and needs to quickly output another? A student in high school? A TA in college? That will orient the reader and set expectations appropriately.

Also show some samples of output, eg Python or Go. It's difficult to assess the tool without understanding how idiomatic the output code is. As in, is USL doing anything more than "tokenizing sed on steroids"? I can't tell.

Then again, if it's meant as a learning tool, maybe it matters less.
