This project was discontinued as Mercurial support has been natively added to the new RAD Studio 10 Seattle. The HgBDS Mercurial Client Library project will still be continued but support for older RAD Studio versions is likely to be dropped since there are no needs to use it in the IDE.
The HgBDS Mercurial Integration package is the main product of this project. Its source code repository is publicly available at Bitbucket. For more information about the repository, see the repository wiki.
