You need Maven 2 installed.
You may just build whole lib.web and site will be built as part of overall building process. If you want site only, steps are not much different: download lib.web distribution, unzip it, enter lib.jar subdirectory and run mvn site command:
$ wget http://dimgel.ru/lib.web/files/lib.web-0.3.3.tar.bz2 $ tar xjf lib.web-0.3.3.tar.bz2 $ cd lib.web-0.3.3/lib.jar $ mvn site
Site will be created in target/site subdirectory:
$ cd target/site $ firefox index.html
Please note that you will get local site version actual for distribution version you downloaded. Latest site version actual for latest lib.web version may be browsed online at http://dimgel.ru/lib.web.
