# Ensure file names do not include paths to repo directory
sed -i -e 's-^./--g' $REPO/PULP_MANIFEST
sed -i -e "s-^$REPO--g" $REPO/PULP_MANIFEST
echo "Complete."

To avoid issues with directories containing a "-" in the name, change the seperator in the sed-commands to (for example) #.
It would read:
sed -i -e 's#^./##g' $REPO/PULP_MANIFEST
sed -i -e "s#^$REPO##g" $REPO/PULP_MANIFEST
