Gri comes with a few ancillary programs that may be useful. Gri also provides a simple scheme to use other system tools (e.g. `awk'). These are discussed here. And speaking of discussing, this chapter ends with a note about a mail-list Gri discussion group.

(`gri_merge' to merge gri-produced PostScript files, `gri_unpage' to separate the pages of a multi-page file into separate pages
