+/* The date below is automatically updated every day by a bot.  During
+   development, we include the date in the tools' version strings
+   (visible in 'ld -v' etc.) because people build binutils from a
+   variety of sources - git, tarballs, distro sources - and we want
+   something that can easily identify the source they used when they
+   report bugs.  The bfd version plus date is usually good enough for
+   that purpose.
+
+   During development, this date ends up in libbfd and libopcodes
+   sonames because people naturally expect shared libraries with the
+   same soname to have compatible ABIs.  We could bump the bfd version
+   on every ABI change, but that's just another thing contributors and
+   maintainers would need to remember.  Instead, it's much easier for
+   all if the soname contains the date.  This is not perfect but is
+   good enough.
+
+   In releases, the date is not included in either version strings or
+   sonames.  */
