++There's an ongoing effort to write the GDL User's and Developer's guide.
++Currently the documentation covers an automatically-generated list of all available library routines
++and their keywords, about 100 code examples, and a few drafts of library
++routine descriptions and other chapters.
++</p>
++
++<p>
++The documentation is available as a single PDF file (only in English):
++<a href="http://gnudatalanguage.sf.net/gdl.pdf">http://gnudatalanguage.sf.net/gdl.pdf [PDF, 1.2 MiB]</a>
++</p>
++
++<p>
++While GDL itself reached a beta status of development, the documentation
++ is far from reaching an alpha status - help is very welcome!
++Please report any inconsistencies in the documentation as any other
++ bugs in GDL. Please submit new additions to the text (incl. code examples)
++ as patches to GDL (see <a href="support.php">support & feedback</a>).
++</p>
++
++<p>
++As GDL is almost 100% compatible to IDL (although not complete as many subroutines
++ are waiting to be implemented), documentation and tutorials for IDL can also be
++ utilized for GDL (see <a href="resources.php">resources</a>).

++<h2><a href="index.html">Obtaining GDL</a></h2>
++
++<p>
++ GDL compiles "out of the box" on Linux, Mac OS X and several other UNIX systems
++ (see <a href="requirements.php">requirements</a> for details).
++</p>
++
++<p>
++ The source code distribution is available from
++ <a href="http://sourceforge.net/projects/gnudatalanguage/">SourceForge</a>.
++</p>
++
++<p>
++ The latest development version of GDL can be obtained via CVS - consult the
++ <a href="http://sourceforge.net/projects/gnudatalanguage/develop/">SF.net project development page</a>
++ for details. It is also possible to
++ <a href="http://gnudatalanguage.cvs.sourceforge.net/viewvc/gnudatalanguage/gdl/">
++ browse the CVS repository using a web-based interface</a>.
++</p>
++
++<p>
++ There are numerous packaged versions of GDL available for various OSes:

++<h2><a href="index.html">Frequently Asked Questions</a></h2>
++
++<h3>Installation and portability issues</h3>
++<ul>
++<li>
++<a>Is it possible to run GDL on MS-Windows?</a>
++<br>Yes.
++<br>Solution 1: It's possible to compile GDL under Cygwin or e.g. to run GDL under the coLinux platform.
++<br>Solution 2: since GDL 0.9.3, GDL should be compilable under MS-windows thanks to <a>Jeong Bin Park</a>
++Please follow the <a href="http://cyfinity.egloos.com/1727847">instructions described here</a>.
++Feedback realy welcome. Please notice SPAWN functionnalities currently not working, which explain large
++number of FAIL in testsuite.
++<br>N.B.: Due to lack of Windows developer- or user-base there is virtually no testing done on Windows, though. Help welcome!
++ </li>
++ </ul>
++
++<h3>Compatibility with IDL</h3>
++ <ul>
++ <li>
++ <a>Is there an equivalent of IDL Virtual Machine in GDL?</a>
++ <br />
++ No.
++ GDL is free/libre/open-source software.
++ The distinction between a developers' (costly) version and a users' (free) version is not applicable.
++ Any user is free to use the full power of GDL.
++ </li>
++ <li>
++ <a>Is there a way to save/distribute pre-compiled GDL routines (as .sav files in IDL)?</a>
++ <br />
++ No. GDL does not support saving/loading pre-compiled routines yet.
++ It does support saving/loading variables into IDL-compatible .sav files, though.
++ Since compatibility with IDL-saved routines is not going to be possible anyhow,
++ and since the virtual-machine context is not applicable to GDL (see above),
++ implementing routine saving has a low priority.
++ </li>
++ <li>
++ <a>Does GDL support the so-called ''object graphics'', ''function graphics''/''new graphics''?</a>
++ <br />
++ No. GDL supports ''direct graphics'' only.
++ </li>
++ <li>
++ <a>Why does the CATCH statement not work properly in GDL?</a>
++ <br />
++ It's one of very few IDL syntax elements not implemented in GDL yet.
++ </li>
++ </ul>
++
++<h3>Mapping</h3>
++ <ul>
++ <li>
++ <a>Why the continent/country/shoreline boundaries have so poor resolution in comparison with IDL</a><br />
++ Try the HIRES keyword to MAP_CONTINENTS!
++ </li>
++ </ul>

++
++<h2>Introduction</h2>
++
++<p>
++GNU Data Language (GDL) is a free/libre/open source incremental compiler
++ compatible with IDL and to some extent with PV-WAVE.
++Together with its library routines it serves as a tool for data analysis
++ and visualization in such disciplines as astronomy, geosciences and
++ medical imaging.
++GDL is free software licensed under the <a href="http://www.gnu.org/licenses/gpl.html">GPL</a>.
++GDL is developed by an international <a href="credits.php">team</a> of volunteers led by Marc Schellens - the project's founder
++</p>
++
++<p>
++GDL as a language is dynamically-typed, vectorized and has
++ object-oriented programming capabilities.
++GDL library routines handle numerical calculations, data visualisation,
++ signal/image processing, interaction with host OS and data input/output.
++GDL supports several data formats such as netCDF, HDF4, HDF5, GRIB, PNG, TIFF,
++ DICOM, etc.
++Graphical output is handled by X11, PostScript, SVG or z-buffer terminals,
++ the last one allowing output graphics (plots) to be saved in a variety of
++ raster graphics formats.
++GDL features integrated debugging facilities.
++GDL has also a Python bridge (Python code can be called from GDL; GDL can be compiled
++ as a Python module).
++</p>
++
++<p>
++Packaged versions of GDL are available for several Linux and BSD flavours as well as Mac OS X.
++The source code compiles as well on other UNIX systems, including Solaris.
++</p>
++
++<p>
++Other open-source numerical data analysis tools similar to GDL include
++<a href="http://www.gnu.org/software/octave/">GNU Octave</a>,
++<a href="http://www.ncl.ucar.edu/">NCL - NCAR Command Language</a>,
++<a href="http://pdl.perl.org/">PDL - Perl Data Language</a>,
++<a href="http://www.r-project.org/">R</a>,
++<a href="http://www.scilab.org/">Scilab</a>,
++<a href="http://www.scipy.org/">SciPy</a>,
++<a href="http://yorick.sourceforge.net/">Yorick</a> ...
++</p>
++
++<h2>Feature summary</h2>
++
++<p>Full syntax compatibility with IDL up to version 7.1 (for >8.0 see below):</p>
++
++<ul>
++ <li>objects, pointers, structs and arrays,</li>
++ <li>system, common block and assoc variables,</li>
++ <li>all operators and datatypes,</li>
++ <li>_EXTRA, _STRICT_EXTRA and _REF_EXTRA keywords...</li>
++</ul>
++
++<p>Supported IDL 8.0 language elements:</p>
++
++<ul>
++ <li>FOREACH loop</li>
++ <li>negative array indices</li>
++ <li>garbage collection pointers and objects</li>
++ <li>call methods on an object using "." (e. g. object.aMemberProcedure,arg1)</li>
++</ul>
++
++<p>The file input output system is fully implemented<br/>
++(Exception: For formatted I/O the C() sub-codes are not supported yet)</p>
++
++<p>Supported file formats include:</p>
++<ul>
++ <li>netCDF 3 (read/write)</li>
++ <li>HDF4 (read/write)</li>
++ <li>HDF5 (read-only, limited support)</li>
++ <li>IDL SAVE files (supported using the Craig Markwardt's <a href="http://cow.physics.wisc.edu/~craigm/idl/down/cmsvlib.tar.gz">CMSVLIB</a>)</li>
++ <li>FITS files, when Astro Lib. is in the path (<a href="http://www.cv.nrao.edu/fits/data/tests/pg93/NRAO pg93"> test suite</a> OK)</li>
++ <li>various graphic formats (e.g. PNG if compiled with ImageMagick)</li>
++ <li>...</li>
++</ul>
++
++<p>
++Graphical output is partially implemented. The PLOT, OPLOT, PLOTS,
++ XYOUTS, CONTOUR, SURFACE, TVRD and TV commands
++(along with WINDOW, WDELETE, SET_PLOT, WSET, TVLCT) work
++(important keywords, some !P
++system variable tags and multi-plots are supported)
++for X windows, z-buffer and postscript output.
++</p>
++
++<p>GUI support (widgets) is officially provided since the 0.9 version (but it's not complete yet).</p>

++
++<p>The Python interface (see <a href="http://gnudatalanguage.cvs.sourceforge.net/viewvc/gnudatalanguage/gdl/PYTHON.txt">PYTHON.txt</a>) requires:</p>
++<ul>
++ <li><a href="http://www.python.org/">Python</a></li>
++ <li><a href="http://numpy.scipy.org/">Numpy</a></li>
++</ul>
++
++<p>Useful IDL/GDL-written libraries:</p>
++<ul>
++ <li><a href="http://cow.physics.wisc.edu/~craigm/idl/cmsave.html">CMSVLIB</a> (for SAVE and RESTORE)</li>
++ <li><a href="http://cow.physics.wisc.edu/~craigm/idl/fitting.html">MPFIT</a> (fitting)</li>
++ <li><a href="http://idlastro.gsfc.nasa.gov/">Astron Lib</a> (FITS format I/O, astronomy-related procedures)</li>
++ <li><a href="http://physics.mnstate.edu/craig/textoidl/">TeXtoIDL</a> (Greek letters, special symbols, sub/superscripts via TeX commands)</li>
++</ul>
++
++<p>At least g++ 3.2 (or a similar C++ standard conforming
++compiler) is needed for compiling GDL.
++<!--Note that problems were reported with following versions of g++:
++</p>
++<ul>
++ <li>g++ 3.3.1 (problems with static casts)</li>
++ <li>g++ 3.3.5 (buggy nested templates)</li>
++ <li>g++ 3.3 build 1671 shipped with OS X</li>
++</ul>
++<p>
++-->
++Succesfull compilations were reported with Intel C++ compiler and numerous versions
++of GCC including the 3.x and 4.x families, on various UNIX environments including
++Linux, Mac OS X, FreeBSD, OpenSolaris, Cygwin and OpenBSD.
++GCC >= 4.2 is needed for OpenMP.
++</p>
++
++<p>The <a href="http://ftp.gnu.org/pub/gnu/readline/readline-5.0.tar.gz">GNU readline</a>
++library 4.3 or later is needed (GDL should compile
++without it, but it's very inconvenient to use that way, furthermore,
++proper event handling for graphic windows requires readline).<br/>
++OS X 10.4: Note that the the readline library which comes with OS X is <b>
++not</b> GNU readline. You need to install GNU readline and set the --with-readlinedir=DIR option to configure.
++</p>
++
++<p>
++ GDL supports compilation using both the shipped autotools "configure" script as well as using CMake.
++ Consult the <a href="http://gnudatalanguage.cvs.sourceforge.net/viewvc/gnudatalanguage/gdl/README">README</a>
++ and the <a href="http://gnudatalanguage.cvs.sourceforge.net/viewvc/gnudatalanguage/gdl/INSTALL">INSTALL</a>
++ files in the GDL distribution for further details on GDL requirements and configuration.
++</p>
++
++<p>GDL was developed using <a href="http://www.antlr2.org">ANTLR v2</a>
++but unless you want to change the grammar (*.g files) you don't need
++ANTLR. All relevant ANTLR files are included in the package.<br/>
++</p>
++
++<!--
++<p>GDL is currently developed using <a href="http://www.kdevelop.org">KDevelop</a>
++3.5.1 under the GNU/Linux distribution Kubuntu. The KDevelop project file is included in the tarball, so if you
++have KDevelop you should be able to use it with GDL seamlessly.</p>

++<h2><a href="index.html">IDL resources</a></h2>
++
++<p>As GDL is almost 100% compatible to IDL (although not complete as many
++subroutines are waiting to be implemented), resources for IDL can also
++be utilized for GDL.</p>
++
++<p>
++Many IDL resources can be found on the pages run by IDL gurus: <a href="http://www.idlcoyote.com/">David Fanning</a>
++ and <a href="http://michaelgalloy.com/">Michael Galloy</a>,
++ and at the <a href="http://groups.google.com/group/comp.lang.idl-pvwave">comp.lang.idl-pvwave</a> usenet group.
++
++</p>
++<!--
++<p>
++Lots of routines written for IDL can be found with the
++<a href="http://www.astro.washington.edu/deutsch/idl/htmlhelp/"
++target="_self">IDL Libraries Browser</a> many of them should also
++work with GDL.
++</p>
++-->
++
++<p>
++IDL 6.4 documentation is published at the <a href="http://idlastro.gsfc.nasa.gov/idl_html_help/home.html">NASA website</a>.
++Documentation for the current version of IDL is available for download from the <a href="http://ittvis.com">ITTVIS website</a>.
++</p>
++
++<p>
++An IDL online tutorial is available at the Scientific Computing and
++Visualization <a href="http://www.bu.edu/tech/research/training/tutorials/idl/">website</a>.

++<h2><a href="index.html">How to contribute?</a></h2>
++<p>
++ GDL is actively developed and has already a lot of functionality.
++ But it is still in beta state as of July 2011.
++ Even though it can already be used for many tasks, there are many
++ things left to be done.<br/>
++ Any contributions are very welcome. Currently contributions can be made in C/C++, GDL and python.
++ See the files
++ <a href="http://gnudatalanguage.cvs.sourceforge.net/viewvc/gnudatalanguage/gdl/HACKING">HACKING</a>
++ and
++ <a href="http://gnudatalanguage.cvs.sourceforge.net/viewvc/gnudatalanguage/gdl/PYTHON.txt">PYHTON.txt</a>
++ in the GDL root directory.
++</p>
++
++<p>Urgent things to do are:</p>
++<ul>
++ <li>Library functions and procedures</li>
++ <li>Documentation and code examples</li>
++ <li>Completing the graphical output system</li>
++ <li>Testing and test routines written in GDL</li>
++ <li>Enhancing the GUI (widget) functionality</li>
++ <li>Porting GDL to other platforms</li>

+ - support for .SKIP [NSteps] command
++
++0.9.4:
++ - large change in various graphic/plotting keywords:
++ - PLOT, OPLOT: All keywords supported except Z and T3D, Correct handling of log/DATA/NORMAL/DEVICE coordinates and CLIPPING.
++ - PSYMs shapes now identical to IDL's.
++ - PLOTS: idem as above, plus /CONTINUE
++ - XYOUTS: idem as above, one-argument support (XYOUTS,"string"). Enhancement wrt. reference program: color,size,angle,etc of text are vectors.
++ - CONTOUR: Support of all options except ZVALUE, ZAXIS,CELL_FILL, C_ANNOTATIONS, CLOSED, DOWNHILL, IRREGULAR, TRIANGULATION,PATH_***
++ Correct implementation of Z, [X,Y], i.e., contours may be skewed, rotated, etc depending on X and Y.
++ Better than IDL:
++ - a new ZLOG option makes log contours as well.
++ - C_ORIENTATION, C_SPACING are also vectors.
++ - log axes give better results
++ - good contouring of Not-A-Number values in Z and MIN_VALUE/MAX_VALUE
++ - CLIPPING ok.
++ Automatic limits in some cases still different from IDL.
++ - AXIS and boxes in plots: all [XYZ]TICK[***] options supported except TICKV and a few TICKFORMAT specifics.
++ - CURSOR: full support for CURSOR command, which is interruptible by control-c and has all the options.
++ - Added cursor-related functions TVCRS and command EMPTY.
++ - Added DEVICE options CURSOR_CROSSHAIR, CURSOR_STANDARD, CURSOR_ORIGINAL and GET/SET_GRAPHICS_FUNCTION (GXoR, GXand, etc).
++ - Disabled by default the focus in the X11 graphics windows as IDL does and repositioned WINDOWS by default to top-right of screen.
++ - when compiled with Eigen3 library, significant speed improvement in MATRIX_MULTIPLY() (not available now for # operator), especially on multi-cores.
