+"""
+Run a Python script in the directory specified by **ctx.bldnode**.
+
+Select a Python version by specifying the **version** keyword for
+the task generator instance as integer 2 or 3. Default is 3.
+
+If the build environment has an attribute "PROJECT_PATHS" with
+a key "PROJECT_ROOT", its value will be appended to the PYTHONPATH.
+Same a string passed to the optional **add_to_pythonpath**
+keyword (appended after the PROJECT_ROOT).
+
+Usage::
+
+    ctx(features='run_py_script', version=3,
+        source='some_script.py',
+        target=['some_table.tex', 'some_figure.eps'],
+        deps='some_data.csv',
+        add_to_pythonpath='src/some/library')
