-* [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.
-* [llpyg](chore/llpyg): It is used to automatically convert Python libraries into Go packages that `llgo` can import. It depends on `pydump` and `pysigfetch` to accomplish the task.
-* [llgen](chore/llgen): It is used to compile Go packages into LLVM IR files (*.ll).
-* [ssadump](chore/ssadump): It is a Go SSA builder and interpreter.

 Below are the key modules for understanding the implementation principles of `llgo`:
 
-* [llgo/ssa](https://pkg.go.dev/github.com/goplus/llgo/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`.
-* [llgo/cl](https://pkg.go.dev/github.com/goplus/llgo/cl): It is the core of the llgo compiler. It converts a Go package into LLVM IR files. It depends on `llgo/ssa`.
-* [llgo/internal/build](https://pkg.go.dev/github.com/goplus/llgo/internal/build): It strings together the entire compilation process of `llgo`. It depends on `llgo/ssa` and `llgo/cl`.
