Split a multi-page gri output file into separate files.
gri_unpage is used to split a multi-page Gri output file (in which the new page command was used) into separate PostScript files, one for each page.
# gri_unpage name.ps
Creates files name-1.ps, name-2.ps, etc, one for each page of name.ps.
The OPTIONS, available if your 'perl' has 'getopts' library, are: -l -- sets the bounding box to letter page size.
By default, the bounding box size is extracted from the original file, and is used for all newly created files.
1. Bounding box is always the same size (grabbed from the original).
2. Assumes that all Gri fonts are used even if they aren't.
