152 | XML files. Read manpage (man ${PROGRAM}) for more info. |

153 | |

154 | --type=TYPE Specify the file type of FILENAME. Currently supports: |

156 | "gettext/rfc822deb", "gettext/schemas", |

157 | "gettext/scheme", "gettext/xml" |
---|
158 | -l, --local Writes output into current working directory |

159 | (conflicts with --update) |

160 | --update Writes output into the same directory the source file |

162 | --srcdir Root of the source tree |
