+

+The pst-asr package is based on PSTricks and is intended to be

+used by linguists to typeset autosegmental representations. The

+core files are 1) pst-asr.tex, the Tex macro file, 2)

+pst-asr.sty, a LaTex wrapper which calls pst-asr.tex, and 3)

+pst-asr-doc.pdf, the documentation.  The complete Tex source for

+the documentation is zipped into pst-asr-doc-source.zip along

+with README.txt, which has instructions for generating the

+documentation.

+

+The file pst-asr-examples.tex is a LaTex file which contains

+almost all the examples in the documentation, very simply

+formatted (no packages other than pstricks, pst-xkey, and pst-asr

+are used) in order to facilitate user experimentation with

+pst-asr typesetting.  Users should be able to run this file with

+little difficulty if pst-asr is fully installed or is simply

+in the same directory that pst-asr-examples.tex is in.

+pst-asr-examples.pdf shows what the source produces.

+\noindent The source file for this pdf file is {\it
+pst-asr-examples.tex}.  It is written in very simple LaTex, using
+no packages other than those that are absolutely necessary for
+illustrating {\it pst-asr\/}: {\it pstricks}, {\it pst-xkey}, and
+{\it pst-asr} itself.  The hope is that potential {\it pst-asr\/}
+users can easily experiment with the various examples and use
+various bits and pieces as models for there own work.
+
+Most of the examples in {\it pst-asr-doc.pdf\/} are given here,
+in the order in which they appear in that document.  The
+numbering is sequential and differs from the numbering in that
+document.
