Update setup.sh to check if the script is int eh right place in a better way

# Setup script for SUCS website in users' public_html dirs

echo "SUCS website setup script"

# (try and) make sure we're running this from the right place

# SUCS website

# ^ a nasty kludge cause I don't know how to do it more sensibly

# test for the magic phrase on line 7 of this very file

head -n 7 setup.sh 2> /dev/null | tail -n 1 | grep -q "SUCS website"

ls $(pwd)/setup.sh &> /dev/null

if [ $? -ne 0 ]; then echo "Please run this script from its containing directory"; exit; fi

# generate correct .htaccess
