+Deprecation Warning
+-------------------
+
+This code has now been merged into Biopython. Starting from
+Biopython release 1.75, all you need to do to support the formats
+below is to load the `Bio.SeqIO` module.
+
+Consequently, this project will no longer be maintained. It will
+remain available online but will not be updated. All improvements
+and bug fixes will occur in the Biopython repository.
+
+You can still use this module until Biopython 1.75 is released and
+available on your system. After that, loading the `incenp.bio.seqio`
+module will be a no-op and a DeprecationWarning will be emitted.
