    dsynth - Add profile selection options
    
    * Allow the profile to be specified via the DSYNTH_PROFILE env
      variable or via the -p profile option, overriding the default
      in /etc/dsynth.ini.
    
      NOTE: If running more than one dsynth simultaneously on the same
    	machine, the following directives in dsynth.ini must be
    	different:
    
    	Directory_packages
    	Directory_repository
    	Directory_buildbase
    	Directory_logs
    
      NOTE: The Directory_distfiles directive can be shared across
    	any number of running instances without running afoul
    	of colliding fetches.
    
    * Allows easy selection from multiple profiles specified in
      dsynth.ini.
    
    * Create an active .lock file in the buildbase and complain if
      another dsynth is running.
