Committers have write access to the source code repository and can therefore make changes to the official version of the source code. The committers for each project are listed below; these are the people that you might want to contact if you have made a change to the source code that you'd like to share (of course, you are required to share your changes by means of the LGPL, but such a change does not have to be included in the official version if it is of little use to others. In such a case, it suffices to just put a tarball online of your version).
