Options:
  --prefix: Install to the specified prefix (absolute path), default is 
                /usr/local
  --userlib: Installs libtango-user-*.a too. It will also be built if it is 
                missing or older than libtango-base-*.a. Note that this is 
                not necessary if you use DSSS or other build tools for the 
                user part of the Tango API
  --altconf: Use an alternate path component for the DMD conf, "bin" is 
                default, "-" will set it to empty. See also --confprefix
  --altlib: Use an alternate path component for the library files, "lib" is 
                default, "-" will set it to empty.
  --altincl: Use an alternate path component for import files, "include" is 
                default, "-" will set it to empty (will install at PREFIX!)
  --confprefix: Use a specific prefix for where DMD binary resides, otherwise 
                PREFIX is used (absolute path). Note that this combined with 
                --altconf can be used to put dmd.conf somewhere else than 
                together with the binary, either your $HOME or /etc. Note that
                together with the DMD binary seems most stable.
  --libprefix: Use a specific prefix for where libs should be installed, 
                otherwise PREFIX is used (absolute path).
  --inclprefix: Use a specific prefix for where imports should be installed, 
                otherwise PREFIX is used (absolute path).
  --uninstall: Uninstall Tango, switch back to standard Phobos.
  --as-phobos: This will install libtango-base-*.a as lib*phobos.a as per old 
               style. This is default for older DMD installations.
  --verify: Will verify installation.
  --verbose: Will produce various progress output
  --help: Will print this help text.'
