The HgBDS Mercurial Integration Project is producing a version control plug-in package for Embarcadero RAD Studio to use Mercurial as an integrated version control system. Its name stands for the executable file name ‘bds.exe’ which is kept unchanged after the product changed its name from Borland Developer Studio (BDS).
TortoiseHg is a shell extension that let users of Mercurial SCM (Hg) work directly from MS-Windows Explorer. It also includes a command line tool, hgtk, for use on Linux and other platforms.
