The jTree package is an extension of PSTricks which is intended to be used by linguists to typeset complex trees. It consists of three files: pst-jtree.tex, pst-jtree.sty, and pst-jtree-doc.pdf and requires the PSTricks package and the XKeyVal package. jTree is a direct descendent of pst-jftree, but there are major changes: a new tree description language is introduced and the xkeyval package is used to handle parameters. pst-jftree will no longer be maintained and will be placed in the /obsolete subdirectory under PSTricks in CTAN.
