Note that you can specify the directory names where the data files
will be installed, but you cannot rename the data files themselves.
+Each (\var{directory}, \var{files}) pair in the sequence specifies the
+installation directory and the files to install there. If
+\var{directory} is a relative path, it is interpreted relative to the
+installation prefix (Python's \code{sys.prefix} for pure-Python
+packages, \code{sys.exec_prefix} for packages that contain extension
+modules). Each file name in \var{files} is interpreted relative to
+the \file{setup.py} script at the top of the package source
+distribution. No directory information from \var{files} is used to
+determine the final location of the installed file; only the name of

You can specify the \option{data\_files} options as a simple sequence
of files without specifying a target directory, but this is not recommended,
and the \command{install} command will print a warning in this case.
