<tool name="gs">
<summary>
<para>
This Tool sets the required construction variables for working with
the Ghostscript command. It also registers an appropriate Action
with the PDF Builder (&b-link-PDF;), such that the conversion from
PS/EPS to PDF happens automatically for the TeX/LaTeX toolchain.
Finally, it adds an explicit Ghostscript Builder (&b-link-Gs;) to the
environment.
