If you are on a Mac you may have discovered an issue with gro not starting properly because of an old directory structure issue. David Soloviechik uses this AppleScript to solve that problem
tell application "Finder"
set current_path to container of (path to me) as alias
end tell
set dir to (POSIX path of current_path)
do shell script "cd \"" & dir & "\" && gro.app/Contents/MacOS/gro > /dev/null 2>&1 &"
To use this script, put it in a file called run_gro.scpt within the gro directory and then at the command line run
> osascript run_gro.scpt
