+DYNAMICALLY LOADED LIBRARIES FOR BYTECODE EXECUTABLES.
+======================================================
+
+   Some bytecode executables of Coq use the OCaml runtime, which dynamically
+   loads a shared library (.so or .dll). When it is not installed properly, you
+   can get an error message of this kind:
+
+	Fatal error: cannot load shared library dllcoqrun
+	Reason: dllcoqrun.so: cannot open shared object file: No such file or directory
+
+   In this case, you need either:
+     - to set the CAML_LD_LIBRARY_PATH environment variable to point to the
+       directory where dllcoqrun.so is; this is suitable when you want to run
+       the command a limited number of times in a controlled environment (e.g.
+       during compilation of binary packages);
+     - install dllcoqrun.so in a location listed in the file ld.conf that is in
+       the directory of the standard library of OCaml;
+     - recompile your bytecode executables after reconfiguring the location of
+       of the shared library:
+         ./configure -coqrunbyteflags "-dllib -lcoqrun -dllpath <path>" ...
+       where <path> is the directory where the dllcoqrun.so is installed;
+     - (not recommended) compile bytecode executables with a custom OCaml
+       runtime by using:
+         ./configure -coqrunbyteflags -custom ...
+       be aware that stripping executables generated this way, or performing
+       other executable-specific operations, will make them useless.
