Redefine chapter/section and subsection appearance

[Sanders, Maarten (M.J.L.)]

Hi,

This is more latex, but probably someone has an answer quickly. I want
chapter, section and subsections to appear like this (view with a
monospace font):

1.    Chapter
      Her starts the text
      More text.
      .
      .
      .
     
1.1   Section
      Some section text

etc.


So I want the numbering to appear in the margin. Are there any packacges
that deal with this or do I need to redefine the section, subsection,
chapter etc. commands?


met vriendelijke groet / kind regards,
 
Maarten Sanders
