pst-knot: plotting special knots

Save the files pst-knot.sty|tex in a directory, which is part of your local TeX tree. The pro file should go into $TEXMF/dvips/pstricks/ Then do not forget to run texhash to update this tree. For more information see the documentation of your LATEX distribution on installing packages into your local TeX system or read the TeX Frequently Asked Questions: (http://www.tex.ac.uk/cgi-bin/texfaq2html?label=instpackages).

PSTricks is PostScript Tricks, the documentation cannot be run with pdftex, use the sequence latex->dvips->ps2pdf.
