Save the files pst-electricfield.sty|tex|pro in a directory, which is part of your local TeX tree. 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 LATEX distribution or the TeX Frequently Asked Questions: (http://www.tex.ac.uk/cgi-bin/texfaq2html?label=instpackages).

The documentation ------------------- To get a smaller size of the generated pdf file run the Makefile or by hand "pst2pdf <file> --Iext=.png --Iscale=0.5 --DPI=150". This will create eps/pdf/png images in a subdirectory images/ and then using only the png ones for the last _pdflatex_ run. The file size can be reduced to about 20% of the one created with ps2pdf. The pdf file is saved as yfile>-pdf.pdf.

When running the documentation in a traditional way, then uncomment the line (in the preamble)

You can also use the Makefile.latex to create all three languages of the document, or alternatively Makefile.pst2pdf to create them with png imgaes to get smaller file sizes.
