+    #. Able to parse simple constructions (assignments, comments, functions, arrays).

+        This class is heavily based on :mod:`shlex` parser, but instead of strings operates with the
+        :class:`ahriman.models.pkgbuild_patch.PkgbuildPatch` objects. The main way to use it is to call :func:`parse()`

+            >>>     print(f"{patch.key} = {patch.value}")
+
+        It doesn't store the state of the fields (but operates with the :mod:`shlex` parser state), so no shell
