R help - Feb 2012 - parse .ps files with R?

Hi,

Is there a way to parse a postscript (*.ps) file with R (or 
perhaps with some other command-line utility)?

E.g., I have a map in postscript format with lots of 
features, but I just want to extract the coastline and it's 
coordinates.

Any help very much appreciated!  Cheers!
Nick
