MacGhostView is an application for previewing Postscript and encapsulated Postscript files and converting them to other formats. It implements the command line tools gv (ghostview) and gs (ghostscript). Multiple files can be previewed at the same time, each one displayed in its own gv window. Unlike Apple's Preview program, MacGhostView does not convert Postscript files to PDF format and then display the PDF file.
