This package was described in the 2nd edition of ‘LaTeX: A Document Preparation System’, but the LaTeX project team declined to produce the package. For a long time, LaTeX included a ‘pict2e package’ that merely produced an apologetic error message. The new package extends the existing LaTeX picture environment, using the familiar technique (cf. the graphics and color packages) of driver files (at present, drivers for dvips, pdfTeX, LuaTeX, XeTeX, VTeX, dvipdfm, and dvipdfmx are available). The package documentation has a fair number of examples of use, showing where things are improved by comparison with the LaTeX picture environment.
