multilat is a tool for controlled multilateral comparison. See http://brettkessler.com/McDonald for a more detailed description of its theoretical basis and for any auxiliary files and documentation not found distributed with this README. The bare minimum needed to run multilat is: 1. A Java Runtime Environment and a SAX parser. This was developed and tested with Sun's compiler and library, version 1.4.2 and probably requires a version pretty close to that. 2. The multilat.jar file or its contents. 3. At least three data files: a retentions rate file and at least two language files to compare. The multilat home pages contains examples of the latter. Currently the system is a bare-bones batch program with no user interface. Under Linux, a command like the following may work: java -Dorg.xml.sax.driver=org.apache.xerces.parsers.SAXParser \ -jar multilat.jar swadesh-retent.xml ANG.xml LAT.xml > output The program is very very verbose and currently there is no way to reduce the amount of output. However, the web site contains a copy of the Perl script splitFiles.pl which will break it into a series of much smaller XML files, including main.xml, which gives a good executive overview, The Makefile also contains examples of using scripts and XSLT files to convert the output to browsable HTML.
