remove text from body and change subject and author

Hi,

I am relativly new to procmail and got a basic setup
running; at least sorting in all my mailboxes works well for
me.

Now, I read that procmail can even do more :-)
I get a lot of mail from a web-forum which looks like this:

     ------------------------------------------------------------
     OpenFOAM Message Board: OpenFoam: Running / Solving / CFD:
     Memory leak
     ------------------------------------------------------------

      For your info, there is a big memory leak when running
     interFoam with some combinations of differencing schemes,
     amounting approximately to 1 field per time-step.  It took
     me ages to find it and there will hopefully be a bug fix in
     the next release.  In the meantime, please beware.
     
     This refers to the foam release dated 19/Dec/2004 and will
     be present on all platforms.

I would like to get rid of the top and the bottom of the
body text (so actually just keep the stuff between the
second and third '---------'). 

Furthermore I would like to change the subject. Right now it
looks like this:

     OpenFoam: Running / Solving / CFD: Memory leak

For me 'Memory leak' would be enough; which is actually the
first line above the second '-------'.

And finally, I would like to change the author/from according to
the name after the second '------'.


I think procmail is able to do all that, but unfortunately I could find
any example which do this.

Does anybody have an idea or any tips to do this?
