* 12 Nov 1992 - To add justify PS proc
* 13 Nov 1992 - To allocate current font buffer before use
* 10 Dec 1992 - To use AFIwrite for ansi compat on sun
* 6 Apr 1993 - To create a dummy variable block for psuedo
* commands generated by .gm and .gd commands.
* 26 May 1993 - To add stroke command to box routine.
* 13 Jun 1993 - To set the psfm variable by placing a dv command
* into the initial input buffer.
* 12 Jul 1993 - To set the def item list font ptr to null
* 21 Feb 1994 - To open output file just "w"
* To put out the PS routine rightxy for header/footer
* 22 Feb 1994 - To init figure font (ffont)
* 7 Apr 1994 - To seup for TOC now that linelen is points related
* 7 Oct 2000 - To use new AFI tokeniser
* 10 Oct 2001 - To add new justification PS functions
* 13 Jan 2001 - Added sym table support
* 08 Nov 2006 - Some cleanup and now allow default input from stdin.
* 10 Apr 2007 - Memory leak cleanup
* 16 Sep 2007 - added page geometry argument support
* 13 Nov 2007 - Changed the imbed/run() mechanism to better support the
* oneject processing.
* 22 Mar 2011 - Correctly set boty when geometry (-g) is given.
