     NAME
          eqnchar - special character definitions for eqn and neqn

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

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

     DESCRIPTION
          eqnchar contains troff and nroff character definitions for
          constructing characters that are not on all
          phototypesetters.  These definitions are primarily intended
          for use with eqn and neqn; eqnchar contains definitions for
          the following characters:

          citimes   ⊗     langle    <     circle    O
