Scribus will usually be interesting when you want to add some new functionality to Scribus or do some repetitive task. If you want to use a Scribus script, you have to save your script content into a .py
file. For example, if we want to use the text vertical alignment script, stored at this URL http://wiki.scribus.net/index.php/Adjust_a_text_frame_to_fit_its_content you'll have to:
Select the Python code from the website (it is shown with a blue background).
Open your favorite text editor. Be careful, use a real text editor, not a text processor, on Windows, Notepad or Notepad++ will be OK, on Mac, use Smultron or Textwrangler, and on Linux, use gedit, vim, or Kate.
Paste the content inside a new document.
Save this file where you want with a
.py
extension.On the website, read the recommendations or explanations if there are any.
Back in Scribus, do what is needed by the script (here it is having a filled text frame selected) and go to Script | Execute Script...
