External Programs used by L2h

These are the original sources of the external programs used by l2h. Since including the below sources in the l2h binary would triple its download size, these sources are only available online. Copyrights and other legal restrictions may be in the source and/or at the indicated sources. Some parts are governed by the GNU General Public License version 3. Also see the "copyrights" folder in the l2h distributions, especially summary.txt, and/or the installation screens, for more information.

• epstopdf: This is essential for those who need to use xelatex for web pages because they do not use a western european language or use greek. It allows their user images to be converted to the only format that works for xelatex web pages, pdf. epstopdf.zip. See also http://ctan.org/pkg/epstopdf.
• IIJG jpeg library: This is needed to allow web page images with more than 256 colors to be created as jpgs. It is also used in some converters of user images in the convert folder. jpeg-6b.zip and jpeg-9.zip. See also http://www.ijg.org/.
• LaTeX2HTML: This is the main engine for the web page generation in l2h. Modified copies are by default provided integrated in l2h. See the l2hmods folder inside system-files for what sources have been changed and how. latex2html99.2.zip and a sanity check I conducted a long time ago on it. See also http://www.latex2html.org/, latex2html.txt.
• netpbm: This is needed to make the web page images, as well as for converting, say, jpg user images to eps. netpbm-10.6_11.zip, netpbm-10.18.18.zip, and netpbm-10.35.89.tgz, and netpbm-10.47.45.zip. See also http://netpbm.sourceforge.net/ netpbm106.txt, netpbm1018.txt, netpbm1047.txt.
• pdftk: This is essential for those who need to use xelatex for web pages because they do not use a western european language or use greek. It allows the web page images to be made from xelatex output. pdftk-1.44-src.zip, pdftk-1.44-win.zip, and pdftk-2.00-src.zip. See also http://www.pdflabs.com/tools/pdftk-the-pdf-toolkit/
• ps2eps: This is often convenient to fix up broken eps images. ps2eps-1.68.zip See also http://www.tm.uka.de/~bless/ps2eps
• pdftops: This is needed for those who need to use xelatex for web pages because they do not use a western european language or use greek. It allows the web page images to be made from xelatex output. This produces better quality results than the ghostscript version pdf2ps. xpdf-3.03.tar.gz and xpdfbin-win-3.03.zip. See also http://www.foolabs.com/xpdf/
• zip, unzip: This is used if the document folder has a file eps.zip. At the start of l2h this file will be unzipped, and at the and, any eps files will be moved into it. zcr23xN.zip and unz551xN.exe. See also http://www.info-zip.org/, info-zip.html.
