------------------------


The scripts "load/save_sge_config.sh" use one `echo` command to display its usage. The default under Linux's `echo` is not to interpret the
escape sequences and will result in one long line only, although the intention was to have it printed out on several ones. This might be
different on other platforms though. Snippet to get the correct behavior would be to add a "-e" to allow that escape sequences will be
honored (works with the plain /bin/echo or bash's builtin):

INFOTEXT=echo
nonewline=`$INFOTEXT "\n"`
if [ "$nonewline" == "\n" ]; then
    INFOTEXT="echo -e"
fi
