Feedback and thanks

[vindarel]

Hi, thanks for the library. After a few attempts, we got i18n support in our web app, integrated with Djula templates.

Since it was difficult for me to do, I'd like to give a feedback and an example.

The PR is visible here: https://gitlab.com/myopenbookstore/openbookstore/-/merge_requests/19

Utilities: https://gitlab.com/myopenbookstore/openbookstore/-/blob/master/src/i18n.lisp for instance:

• clear the catalogue for development
• see the list of loaded message for a specific locale
• list loaded locales
• set the locale (with a couple checks)
• with-locale macro

credit goes to @fstamour

I'll write more about the process if and when I can.

Best,

---
