Fax document style. Generates a letter style document, with a time stamped cover sheet, and appropriate headers and footers for using LaTeX for facsimile document preparation. Optionally, will insert a postscript signature at the end of the document. (The scanned signature should be 1 in. by 2.5 in., see fax.sty for details.) Requires Piet van Oostrum's fancyheadings.sty, available by anonymous ftp from the CTAN tex-archives. The headers and footers have provision for including document control id's. The rcs.sty package, written by Joachim Schrod, also available from the CTAN archive, works well when using RCS (available by anonymous ftp from prep.ai.mit.edu in /pub/gnu) as a document control system. Fax.sty is a modification to letter.sty, by Leslie Lamport, and is available from the CTAN tex-archives in the standard distribution for LaTeX. The diff's, letter-fax.diff, are supplied. See the source for usage and template. Letterhead.sty generates first fax page header and footers, and was derived from "A Guide to LaTeX," Helmut Kopka and Patrick W. Daly, Addison-Wesly, 1993, pp. 231-243. See the source for usage and template. Fax.sty and letterhead.sty, along with rcs.sty, fancyheadings.sty, and dvips have been used extensively with Ed Casas' efax package, available from by anonymous ftp to sunsite.unc.edu in /pub/Linux/apps/comm. (Efax is quite portable, and is known to compile on AIX 3.2.4, BSD, IRIX 5.2, NeXT, OSF/1V1.3, SunOS 4.1.1/4.1.3, SCO 3.2.0, SysVR4.2, ULTRIX and should work with minor changes on any modern UNIX with an ANSI C compiler/library and a termios(4) serial device interface.) To use the package, you will need ghostscript, (available from prep.ai.mit.edu) dvips (available from the CTAN archive,) and probably the pbm utilities, if it is desired to fax postscript/eps files. john@email.johncon.com (John Conover)
