A tree program is available by ftp from uhccux.uhcc.hawaii.edu in
directory "linguist" in file "tree1.1.tar.Z" which produces either
on-screen diagrams of trees (examples below) or plain TeX code.
From either input,

\tree
A
  B
    C
    D
    E
      F
      G
      H
    I
  J
  K
    L
      M
      N

or input

\tree (A(B(C)(D)(E(F)(G)(H))(I))(J)(K(L(M)(N))))

it produces for on-screen display this,

         A
    _____|_____
    |    |    |
    B    J    K
____|_____    |
|  |  |  |    L
C  D  E  I   _|__
   ___|___   |  |
   |  |  |   M  N
   F  G  H

or this,
                     A
         ____________|____________
         |           |           |
         B           |           K
_________|_________  |           |
|     |     |     |  |           L
|     |     E     |  |          _|__
|     |  ___|___  |  |          |  |
|     |  |  |  |  |  |          |  |
C     D  F  G  H  I  J          M  N

or this,
           A
      _____|_____
      |    |    |
     B|    J   K|
______|______   |
|   |   |   |  L|
C   D  E|   I  _|__
     ___|___   |  |
     |  |  |   M  N
     F  G  H

or other variants, and corresponding prettier versions using TeX.
For the latter, versions with slanty lines require a PostScript printer.
