 - With Petclinic website, it is possible to add pets, visits to clinic, etc. There is no login system, it is possible to add to database directly at website http://127.0.0.1:8000/ or http://YOUR-COMPUTER-IP-ADDRESS:8000/
 - When xet7 added issue about blink segfault at s390x, 5 minutes later jart added fix https://github.com/jart/blink/issues/162
-- Blink is x86_86 emulator, similar to qemu https://github.com/jart/blink . With blink, it works at Linux s390x. Without blink, it works at x86_86/arm64 Win/Mac/Linux/BSD, but ASAN security feature does not work yet at arm64, like mentioned at Makefile of https://github.com/xet7/pet . If there is errors, maybe you need to run it with `chmod +x redbean.co && sh -c ./redbean.com`, or also need to install `ape` from https://github.com/jart/cosmopolitan .

 - Redbean is webserver https://redbean.dev
 - Fullmoon is Lua web framework https://github.com/pkulchenko/fullmoon . Petclinic has fork of Fullmoon, making possible to use SQLite across CGI-like Lua processes of Redbean, like mentioned at Readme https://github.com/xet7/pet
 - By using Makefile with `make all` or `make start` it makes one executeable. When starting, it creates SQLite database to same directory, adding data, with `srv/.lua/*.sql`
