186Usage: ${PROGRAM} [OPTION]... PO_DIRECTORY FILENAME OUTPUT_FILE
187Generates an output file that includes some localized attributes from an
188untranslated source file.
189
190Mandatory options: (exactly one must be specified)
191  -b, --ba-style         includes translations in the bonobo-activation style
192  -d, --desktop-style    includes translations in the desktop style
193  -k, --keys-style       includes translations in the keys style
194  -s, --schemas-style    includes translations in the schemas style
195  -r, --rfc822deb-style  includes translations in the RFC822 style
196  -x, --xml-style        includes translations in the standard xml style
197
198Other options:
199  -u, --utf8             convert all strings to UTF-8 before merging
200                         (default for everything except RFC822 style)
201  -p, --pass-through     deprecated, does nothing and issues a warning
202  -m, --multiple-output  output one localized file per locale, instead of
203                         a single file containing all localized elements
204  -c, --cache=FILE       specify cache file name
205                         (usually \$top_builddir/po/.intltool-merge-cache)
206  -q, --quiet            suppress most messages
207      --help             display this help and exit
208      --version          output version information and exit
