When on Mac OS calling tar as per the script

        gm-backup_database.sh

the flags

        -cfW

do not work as intended. W (verify) is not supported and, with only -cf on Mac, 
one gets an uncompressed .tar archive.

1. would you be happy to insert in

        gm-backup_database.sh

beneath

        # tar and test it 

the comment

        # Note: Mac OS requires 'tar -cjf'


2. where the script says

        # tar and test it
        if test -z ${VERIFY_TAR} ; then
                tar -cf ${BACKUP_FILENAME}.tar ${BACKUP_FILENAME}-database.sql 
${BACKUP_FILENAME}-roles.sql
        else
                tar -cWf ${BACKUP_FILENAME}.tar ${BACKUP_FILENAME}-database.sql 
${BACKUP_FILENAME}-roles.sql
        fi ;

doesn't the test -z ${VERIFY_TAR} mean 'if verification is desired' in which 
case doesn't the W flag belong with the 'if' instead of in the 'else' ?
