Notifications of all changes you make will be sent to the dev@commons mailing list, so we will be aware of your changes and we will happily correct any small mistakes that you might make. |
We're a Commons community, dedicated to creating reusable library components in Java. Apache Commons is now using Subversion as the version control system.
