My first official participation in open source made it online today. Jeff Breidenbach and I have updated the lucene source package for Lucene uploaded to Debian. This release is 1.4.3-2, based upon the upstream sources for 1.4.3.
For those who aren't into this stuff, this is basically a piece of software known as a library, which is used by other programs to perform searching, somewhat like Google does. Packaging it for Debian GNU/Linux means that we take the software and package it in such a way that Debian and Debian-based Linux distributions can install the software easily without creating conflicts or failing to ensure that any dependencies have been met.
Lucene is an open source Java library. Currently, our package only compiles with the Sun 1.4.x JDK. The next big initiative is to get it to build and test with open source Java compilers and Java virtual machines (JVMs). The first JVM to test will probably be Kaffe, followed by SableVM.
