Configuring Personal Web Server MIME types.

I am trying to configure Personal Web Server (PWS) to work with RealNetworks Realserver G2 for streaming audio, on a Win '95 computer, however, it requires that I do the following:

define the following MIME types on your Web server:

audio/x-pn-realaudio (files with a .ra, .rm or .ram file extension)
audio/x-pn-realaudio-plugin (files with a .rpm file extension)
application/smil (files with a .smi or .smil extension)
application/sdp (files with a .sdp extension)
application/x-pn-realmedia (files with .rp, extension)
text/html (files with a .html or .htm extension)
image/gif (files with a .gif extension)
image/jpg (files with a .jpg or .jpeg extension)

Can anyone tell me exactly how to configure the MIME types for PWS so that it will include these types.
