Pywikibot has a pwb code entry point i.e. pwb.exe in <pythonpath>/Scripts. This wrapper script is able to call any script found in following folders:

• config.user_script_paths in base directory
• base directory (see https://doc.wikimedia.org/pywikibot/master/api_ref/pywikibot.config.html#config.get_base_dir)
• pywikibot.scripts folder

The entry point works for script within pwikibot.scripts:

pwb version

but fails for framework scripts:

pwb redirect do
ERROR: redirect.py not found! Misspelling?

To run the script one has to invoke it with:

pwb.py redirect do

(note the .py)

pwb.py usually resides in the topmost Pywikibot folder. Both should call the wrapper script.
