-    (description "This module provides an @code{xopen} function that works like
-     Python's built-in @code{open} function, but can also deal with compressed files.
-     Supported compression formats are gzip, bzip2 and, xz, and are automatically
-     recognized by their file extensions.  The focus is on being as efficient as
-     possible on all supported Python versions.")
