docs: def get_version(path=None, module=None):
      """Return the version string.
  
      This function ensures that the version string complies with PEP 440.
      The format of our version string is:
  
          - for RELEASE builds:
              <major>.<minor>
            e.g.
              0.1
              2.4
  
          - for DEVELOPMENT builds:
              <major>.<minor>.dev<num_branch_commits> \
              +<branch_name>.g<short_git_sha>[.dirty]
            e.g.
              1.1.dev34+new.shiny.feature.gfa973da
              0.1.dev7+master.gb91ffa6.dirty
  
          - for UNKNOWN builds:
              0.0+unknown.[<scm_type>.]<date>
            e.g.
              0.0+unknown.svn.201402031023
              0.0+unknown.201602081715
  
      The <major>.<minor> substring for development builds will be that of the
      NEXT (minor) release, in order to allow proper Python version ordering.
  
      Parameters
      ----------
      path : None or string, optional
          A file or directory to use to find the SCM or sdist checkout path
          (default is the current working directory)
      module : None or string, optional
          Get version via module name (e.g. __name__ variable), which takes
          precedence over path if provided (ignore otherwise)
  
      Returns
      -------
      version: string
          A string representation of the package version
