 - `libghdl` is a shared library that includes a subset of the regular features plus some features to be used by extension tools (i.e. `libghdl-py`). This is built along with the regular GHDL and it supports both non-synthesisable and synthesisable code. Nonetheless, this is not for users, but for tools built on top of the core. When configured along with `--enable-synth`, this shared library includes **[experimental]** synthesis features too.

+# pyGHDL
+
+Python binding for GHDL and high-level APIs.
+
+## Provided Packages
+
+* `pyGHDL.cli` - Command line interface tools.
+* `pyGHDL.dom` - Document Object Model (DOM) for VHDL parsed by `libghdl`.
+* `pyGHDL.libghdl` - Low-level Python bindings to GHDL's `libghdl` shared library.  
+	Auto generated API from Ada sources.
+* `pyGHDL.lsp` - Language Server Protocol (LSP) implementation for VHDL.
