 1. Before opening a new [Github issue](https://github.com/JuliaLang/julia/issues):
   - Try searching the existing issues or the [`julia-users` mailing list](https://groups.google.com/forum/#!forum/julia-users) to see if someone else has already noticed the same problem.
   - Try some simple debugging techniques to help isolate the problem.
-    - Try running the code with the debug REPL. If you have a source distribution of Julia, you can build your own debug REPL with `make debug`, which produces the `usr/bin/julia-debug-basic` and `usr/bin/julia-debug-readline` REPLs.
+    - Try running the code with the debug REPL. If you have a source distribution of Julia, you can build your own debug REPL with `make debug`, which produces the `usr/bin/julia-debug-basic` REPL.
     - Consider running the debug REPL in a debugger such as `gdb` or `lldb`. Obtaining even a simple [backtrace](http://www.unknownroad.com/rtfm/gdbtut/gdbsegfault.html) is very useful.
     - If Julia segfaults, try following [these debugging tips](https://gist.github.com/staticfloat/6188418#segfaults-during-bootstrap-sysimgjl) to help track down the specific origin of the bug.
