    <para>
      <application>Asymptote</application> is a powerful descriptive vector
      graphics language that provides a natural coordinate-based framework for
      technical drawing. Labels and equations can be typeset with LaTeX.  As
      well as EPS, PDF and PNG output it can produce WebGL 3D HTML rendering
      and (using <application>dvisvgm</application>) SVG output.

      <!-- This is specifically about my cylinder test - it has been
       broken twice, one time the fix involved changing the script,
       the second was blamed on the low-end hardware (radeon 3400G).
       I don't use, or understand the commands of, asy so I will not
       spend time bisecting it.  Ken -->

<!-- Editors: for testing this, the minimal latex functionality is
 covered by the cylinder and triangle tests in

    <para>
      <parameter>--libdir=$TEXLIVE_PREFIX/texmf-dist</parameter>:
      This parameter ensures that the <filename
      class="directory">asymptote</filename> directory will similarly
      overwrite any files installed by install-tl-unx.
    </para>

     <para>
       <parameter>--disable-lsp</parameter>: The Language Server Protocol is
       enabled by default, with several third-party sources included, but it
       does not build unless boost and repidjson have been installed.
     </para>

    <para>
      <parameter>--enable-gc=system</parameter>: this ensures that the system
      version of <filename class="libraryfile">libgc.so</filename> will be used
      instead of the version shipped with this package.
    </para>

    <para>
      <parameter>--with-latex=</parameter>
      <parameter>--with-context=</parameter>: These switches
      ensure that style files and a tex file will be installed into the
      <application>texlive</application> directories instead of creating a
      <filename class="directory">texmf-local</filename> directory for them.
    </para>

    <!-- commenting for now: 2.44 installs asymptote.info in both places
     so the old version no longer remains

    <para>
      <command>rm -fv /opt/texlive/.../asymptote.info</command>:
      This deletes the file installed by <application>texlive</application>.
      Exceptionally, asymptote will create an <filename
      class="directory">asymptote/</filename> subdirectory for its own
      <filename>asymptote.info</filename> even though a possibly older
      version from <xref linkend="texlive"/> is in the main
      <application>texlive</application>
      <filename class="directory">info/</filename> directory. Both the
      new version and the existing <filename>asy-faq.info</filename>
      <emphasis>will</emphasis> be found by <command>info</command>.
