1.0+beta14 (11/10/2017)

• Add (copy_files ) and (copy_files# ) stanzas. These
  stanzas setup rules for copying files from a sub-directory to the
  current directory. This provides a reasonable way to support
  multi-directory library/executables in jbuilder (#35, Francois Bobot)

• An empty jbuild-workspace file is now interpreted the same as one
  containing just (context default)

• Better support for on-demand utop toplevels on Windows and when the
  library has C stubs

• Print Entering directory '...' when the workspace root is not the
  current directory. This allows Emacs and Vim to know where relative
  filenames should be interpreted from. Fixes #138

• Fix a bug related to menhir stanzas: menhir stanzas with a
  merge_into field that were in jbuild files in sub-directories
  where incorectly interpreted (#264)

• Add support for locks in actions, for tests that can't be run
  concurrently (#263)

• Support ${..} syntax in the include stanza. (#231)
