174 Usage: %s [OPTION]... FILE...\n\
176 Arguments to long options also apply to equivalent short options.\n\
179 -o, --output=FILE output to FILE, default format from FILE's name\n\
180 -O format=FORMAT override format for previous -o\n\
181 -O OPTION=VALUE set output option to customize previous -o\n\
182 -O device={terminal|listing} override device type for previous -o\n\
183 -e, --error-file=FILE append errors, warnings, and notes to FILE\n\
184 --no-output disable default output driver\n\
185 Supported output formats: %s\n\
188 -I, --include=DIR append DIR to search path\n\
189 -I-, --no-include clear search path\n\
190 -r, --no-statrc disable running rc file at startup\n\
191 -a, --algorithm={compatible|enhanced}\n\
192 set to `compatible' if you want output\n\
193 calculated from broken algorithms\n\
194 -x, --syntax={compatible|enhanced}\n\
195 set to `compatible' to disable PSPP extensions\n\
196 -b, --batch interpret syntax in batch mode\n\
197 -i, --interactive interpret syntax in interactive mode\n\
198 --syntax-encoding=ENCODING specify encoding for syntax files\n\
199 -s, --safer don't allow some unsafe operations\n\
200 Default search path: %s\n\
202 Informative output:\n\
203 -h, --help display this help and exit\n\
204 -V, --version output version information and exit\n\
