The jTree package is an extension of PSTricks which is intended to be used by linguists as a tool to typeset complex trees. It consists of 6 files: pst-jtree.tex, pst-jtree.sty, pst-jtree-examples.tex, pst-jtree-doc.pdf, pst-jtree-doc-add.pdf (which is essentially an appendix to the older pst-jtree-doc.pdf), and a zip file containing the source code for the documentation.
