+
+- **Kvara** means *fourth* in Esperanto.
+- **Kvara** rhymes with Uxn's *Varvara*.
+- **Kvara** is the fourth Uxntal assembler that I have used, the others were:

+- **Kvara** is also a reference to the *Forth* programming langauge, which led

-- Kvara supports `\ comment` (backslash+space) Forth style comments, these are not 
-  part of the Uxntal specification which only support `( comment )` 
-  (there must whitespace after the opening `( ` and closing ` )` parenthesis)
