Specifies a common physical directory that dmake can write temporary output files to and read temporary output files from. The directory used is $(HOME)/.dmake and this or whichever directory is specified, must be visible to all build servers.
Use this option only if the $(HOME) directory on your local host and the $(HOME) directory on all of your remote hosts are not the same physical $(HOME) directory. For example, a root user would use this option.
