+produce PostScript drawings from within TeX and LaTeX.  TeXdraw has been
+designed to be extensible.  Drawing segments are relocatable, self-contained
+units.  Using a combination of TeX's grouping mechanism and the
+@code{gsave}/@code{grestore} mechanism in PostScript, drawing segments allow
+for local changes to the scaling and line parameters.  Using TeX's macro
+definition capability, new drawing commands can be constructed from drawing
+segments.")
