"If multiple input files are specified, they are merged with\n"
"translations from later files taking precedence.\n\n"
"Options:\n"
" -h\n"
" -help Display this information and exit.\n\n"
" -i <infile>\n"
" -input-file <infile>\n"
" Specify input file. Use if <infile> might start with a dash.\n"
" This option can be used several times to merge inputs.\n"
" May be '-' (standard input) for use in a pipe.\n\n"
" -o <outfile>\n"
" -output-file <outfile>\n"
" Specify output file. Default is '-' (standard output).\n\n"
" -if <informat>\n"
" -input-format <format>\n"
" Specify input format for subsequent <infile>s.\n"
" The format is auto-detected from the file name and defaults to 'ts'.\n\n"
" -of <outformat>\n"
" -output-format <outformat>\n"
" Specify output format. See -if.\n\n"
" -drop-tags <regexp>\n"
" Drop named extra tags when writing TS or XLIFF files.\n"
" May be specified repeatedly.\n\n"
" -drop-translations\n"
" Drop existing translations and reset the status to 'unfinished'.\n"
" Note: this implies --no-obsolete.\n\n"
" -source-language <language>[_<region>]\n"
" Specify/override the language of the source strings. Defaults to\n"
" POSIX if not specified and the file does not name it yet.\n\n"
" -target-language <language>[_<region>]\n"
" Specify/override the language of the translation.\n"
" The target language is guessed from the file name if this option\n"
" is not specified and the file contents name no language yet.\n\n"
" -no-obsolete\n"
" Drop obsolete messages.\n\n"
" -no-finished\n"
" Drop finished messages.\n\n"
" -no-untranslated\n"

" -sort-contexts\n"

" -sort-messages\n"
