      NAME
	   eqnchar - special character definitions for eqn and neqn

      SYNTAX
	   eqn /usr/pub/eqnchar	[ files	] | troff [ options ]

	   neqn	/usr/pub/eqnchar [ files ] | nroff [ options ]

	   eqn -Taps /usr/pub/apseqnchar [ files ] | troff [ options ]

	   eqn -Tcat /usr/pub/cateqnchar [ files ] | otroff [ options ]

      DESCRIPTION
	   Eqnchar contains troff(1) and nroff(1) character definitions
	   for constructing characters that are	not available on a
	   phototypesetter.  These definitions are primarily intended
	   for use with	eqn(1) and neqn; eqnchar contains definitions
	   for the following characters:

	   ciplus    ciplus	     ||	   ||	     squaresquare
	   citimes   citimes	     langle	     langlecirclecircle
	   wig	     wig   rangle    rangle	     blotblot
	   -wig	     -wig  hbar	     hbar  bullet    bullet
	   >wig	     >wig  ppd	     ppd   prop	     prop
	   <wig	     <wig  <->	     <->   empty     empty
	   =wig	     =wig  <=>	     <>	   member    member
	   star	     star  |<	     |<	   nomem     nomem
	   bigstar   bigstar	     |>	   |>	     cupcup
	   =dot	     =dot  ang	     ang   cap	     cap

	   Apseqnchar is a version of eqnchar tailored for the
	   Autologic APS-5 phototypesetter.  This will not look	optimal
	   on other phototypesetters.  Until a phototypesetter-
	   independent version of eqnchar is available,	eqnchar	should
	   be a	link to	the default version on each system.  The
	   standard default is apseqnchar.

      FILES
	   /usr/pub/eqnchar
	   /usr/pub/apseqnchar
	   /usr/pub/cateqnchar

      SEE ALSO
	   eqn(1), nroff(1), troff(1).
