NuxDocument is a Zope product that represents generic documents by using plugins to convert native productivity suite formats to HTML (for viewing or previewing in a regular browser) or to plain text (for indexing).
NuxDocument is designed to run on Linux/Unix platforms, and uses external utilities wrapped in Python "plugins" to perform actual conversion.
Needs: wvWare (http://www.wvware.com), xlhtml (http://www.xlhtml.org/) and ppthtml (http://www.xlhtml.org/ too).
Needs: xsltproc from libxml2 (http://xmlsoft.org/XSLT/) and unzip.
Needs: GNU unRTF (http://www.gnu.org/directory/GNUunRTF.html).
Needs: xpdf (http://www.foolabs.com/xpdf/).
Note that the lynx web browser (www.lynx.org) is also needed to run most of the NuxDocument plugins.
NuxDocument is an extension of Eric Barroca's MSWordDocument. It's CMF aware but limited to Unix/Linux-like platforms. It needs external programs to actually do the conversions.
NuxDocument can be optionnaly internationalized using Localizer, (http://www.nuxeo.org/localizer), though that's not mandatory anymore.
