-Compiler front end of drift language.
+The Drift Programming Language.
 
 1. Written in pure C99 version.
-2. A single compiled file compiles the source code into a bytecode file.
+2. Bytecode execution.
 3. For the drift language, see my blog post:
      https://bingxio.fun/article/2021-05-24.html
-4. The generated bytecode file runs on a virtual machine in any language.
-5. Represents a runtime that can be used in other languages.
-6. The compiler is only about 50 kb size and can only run on any device.
+4. After optimization, the size is only about 15 kb.
+5. The compiler runs on any device.
+6. Provide external interfaces to access languages libraries
+     that support links.
+7. Minimalist language implementation.
