+         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.

+    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.
+    Reported by Christer Solskogen.
