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