that can be used
      with Universal Windows Platform (UWP) Apps and published to the store

  From Daniel Holth:

      metaclass on PyPy); wrap most-used open() calls in 'with' statements to

      It can be downloaded separately at
      https://github.com/Microsoft/vswhere

    - Fixed the issue with LDMODULEVERSIONFLAGS reported by Tim Jennes
      (https://pairlist4.pair.net/pipermail/scons-users/2016-May/004893.html).
      An error was causing "-Wl,Bsymbolic" being added to linker's command-line
      even when there was no specified value in LDMODULEVERSION and thus no
      need for the flags to be specified.
    - Added LoadableModule to the list of global functions (DefaultEnvironment
      builders).

  From Manish Vachharajani:
    - Update debian rules, compat, and control to not use features

as a package
    - Added additional documentation to the user manual on using
toolpaths with the environment
      This includes the use of sys.path to search for tools installed
via pip or package managers
    - Added support for a PyPackageDir function for use with the toolpath

  From Russel Winder:
    - Reordered the default D tools from "dmd, gdc, ldc" to "dmd, ldc, gdc".
    - Add a ProgramAllAtOnce builder to the dmd, ldc, and gdc tools. (PR #448)
    - Remove a file name exception for very old Fedora LDC installation.
    - gdc can now handle building shared objects (tested for version 6.3.0).
    - Remove establishing the SharedLibrary builder in the dmd, ldc, and gdc
      tools, must now include the ar tool to get this builder as is required for
      other compiler tools.
    - Add clang and clang++ tools based on Paweł Tomulik's work.
