Greenstone Interface Pack
Greenstone2.63 and later: Greenstone now comes with all languages enabled. New HTML and CSS stylesheets have removed the need for images with text on them, reducing the size of each language interface. This "classic interface" pack contains all the old text images (for all languages), and is designed to be used with a backwards compatibility macro file. You will only need to download this pack if you want to use the old-style tables + text images layout, or if you need support for Netscape 4, which doesn't support the new CSS. To use the images, edit greenstoneetcmain.cfg, and replace nav_css.dm with nav_ns4.dm in the macrofiles list. Note that this does not affect the multilingual support for the Greenstone Librarian Interface.
Greenstone Language Pack
Greenstone2.62 and earlier: These versions of Greenstone come with only English, French, Spanish and Russian reader's interfaces. This following three packages contain the interface to Greenstone in various different language versions; see here for details. Note that this does not affect the multilingual support for the Greenstone Librarian Interface.
Export to CD-ROM
Greenstone2.70: This package enables the "export to CD-ROM" function from within the Greenstone Librarian Interface and the Collector. This has been included in all binary releases since 2.70w. To get this functionality for Greenstone versions prior to 2.70, please contact the mailing list.
To install, simply download the file (it will work on both Windows and Unix/Linux) and extract the zip archive into your existing Greenstone installation folder's bin/windows directory. (It goes into the bin/windows directory regardless of whether you are working on Linux or Windows.)
