-    stdio: don't assume gets any more
-    
-    Gnulib intentionally does not have a gets module, and now that C11
-    and glibc have dropped it, we should be more proactive about warning
-    any user on a platform that still has a declaration of this dangerous
-    interface.
-    
-    * m4/stdio_h.m4 (gl_STDIO_H, gl_STDIO_H_DEFAULTS): Drop gets
-    support.
-    * modules/stdio (Makefile.am): Likewise.
-    * lib/stdio-read.c (gets): Likewise.
-    * tests/test-stdio-c++.cc: Likewise.
-    * m4/warn-on-use.m4 (gl_WARN_ON_USE_PREPARE): Fix comment.
-    * lib/stdio.in.h (gets): Make warning occur in more places.
-    * doc/posix-functions/gets.texi (gets): Update documentation.

-      Libchop is a set of utilities and library for data backup and
-      distributed storage.  Its main application is chop-backup, an
-      encrypted backup program that supports data integrity checks,
-      versioning at little cost, distribution among several sites,
-      selective sharing of stored data, adaptive compression, and more.
-      The library itself, which chop-backup builds upon, implements
-      storage techniques such as content-based addressing, content hash
-      keys, Merkle trees, similarity detection, and lossless compression.
-      It makes it easy to combine them in different ways.  The
-      ‘chop-archiver’ and ‘chop-block-server’ tools, illustrated in the
-      manual, provide direct access to these facilities from the command
-      line.  It is written in C and has Guile (Scheme) bindings.
