    <title>Introduction to PDL</title>

    <para><application>PDL</application> (Perl Data Language) gives
    standard <application>Perl</application> the ability to compactly store
    and quickly manipulate the large N-dimensional data arrays common to
    scientific computing. <application>PDL</application> turns
    <application>Perl</application> into an array-oriented, numerical language
    similar to such commercial packages as <application>IDL</application>
    and <application>MatLab</application>. One can write simple
    <application>Perl</application> expressions to manipulate entire numerical
    arrays all at once.</para>

    <para><application>PDL</application> provides extensive numerical and
    semi-numerical functionality with support for two- and three-dimensional
    visualisation as well as a variety of I/O formats. The goal is to allow
    <application>PDL</application> to interact with a variety of external
    numerical packages, graphics and visualisation systems. Easy interfacing
    to such systems is one of the core design features of
    <application>PDL</application>.</para>

    <bridgehead renderas="sect3">PDL Dependencies</bridgehead>

    <para><application>PDL</application> is a collection of over 90
    <application>Perl</application> modules. Some of these modules require
    additional libraries, packages and/or <application>Perl</application>
    modules for full functionality. Listed below are the modules which require
    additional software or configuration. If you don't need a particular
    module's functionality, you don't need to install its dependencies. The
    dependency tree for each module is listed downward, meaning you'll need to
    start at the bottom of a module's tree and work up. The dependencies are
    listed in the same order as they are in the
    <filename>DEPENDENCIES</filename> file, found in the package source
    tree.</para>

    <para>This package (and many of the dependency packages) requires a Fortran
    compiler for full functionality of all the different modules. The
    <command>gfortran</command> compiler installed with the current BLFS
    version of <application>GCC</application> (&gcc-version;) will not work. If
    you want to compile the parts of this package that require a Fortran
    compiler, you'll need to install a
    <application>GCC</application>-3.x.x version of Fortran. The
    <application>GCC</application> developers recommend using Fortran from
    <application>GCC</application>-3.4.6. You can find specific instructions
    to install a <application>GCC</application>-3.4.6 compiler on the
    <ulink url="&blfs-wiki;/gcc3">BLFS
    Wiki</ulink>. Alternatively, if you have a need to install
    <xref linkend="gcc3"/>, you can add the Fortran compiler to the list of
    compilers installed in those instructions. Don't forget to put the
    directory containing the <command>{g,f}77</command> commands at the
    beginning of your <envar>PATH</envar> environment variable before
    beginning the compilation.</para>

    <bridgehead renderas="sect4">PDL::NiceSlice</bridgehead>

    <para>The <application>PDL</application>::NiceSlice module is used to
    enhance <application>PDL</application>'s slice syntax.
    <quote>Slicing</quote> is a term used in the process of creating a
    cross-section, or slice, of a <application>PDL</application> object
    (piddle).</para>
