  on by default. 
  
* MINOR CHANGE: Allow unix systems to use `rsync` instead of `cp` for fetching the qsub output.

* MINOR CHANGE: `qsub_retrieve()` now uses pbapply when loading in the output.

* BUG FIX: Test ssh connection pointer before using it.

* BUG FIX: Do not remove the first line of an error file.

* MINOR CHANGE: Use absolute paths to output standard output and error logs (#16, suggested by @mmehan).
