+"""Generate nxlib API documentation as Markdown using pydoc-markdown.
+
+Output is written as one .md file per module under the given build directory,
+mirroring the package layout (e.g. nxlib/nxopen/uf.md). No import of nxlib
+is required (pydoc-markdown parses source via docspec), so NXOpen need not be
+installed.
