+* [pydump](chore/_xtool/pydump): It's the first program compiled by `llgo` (NOT `go`) in a production environment. It outputs symbol information (functions, variables, and constants) from a Python library in JSON format, preparing for the generation of corresponding packages in `llgo`.
+* [pysigfetch](https://github.com/goplus/hdq/tree/main/chore/pysigfetch): It generates symbol information by extracting information from Python's documentation site. This tool is not part of the `llgo` project, but we depend on it.

 Below are the key modules for understanding the implementation principles of `llgo`:
 
-* [ssa](https://pkg.go.dev/github.com/goplus/llgo/compiler/ssa): It generates LLVM IR files (LLVM SSA) using the semantics (interfaces) of Go SSA. Although `LLVM SSA` and `Go SSA` are both IR languages, they work at completely different levels. `LLVM SSA` is closer to machine code, which abstracts different instruction sets. While `Go SSA` is closer to a high-level language. We can think of it as the instruction set of the `Go computer`. `llgo/ssa` is not just limited to the `llgo` compiler. If we view it as the high-level expressive power of `LLVM`, you'll find it very useful. Prior to `llgo/ssa`, you had to operate `LLVM` using machine code semantics. But now, with the advanced SSA form (in the semantics of Go SSA), you can conveniently utilize `LLVM`.
