install-info --help (return code: 0)
Usage: install-info [OPTION]... [INFO-FILE [DIR-FILE]] Add or remove entries in INFO-FILE from the Info directory DIR-FILE. INFO-FILE and DIR-FILE are required unless the --info-file or --dir-file (or --info-dir) options are given, respectively. Options: --add-once add only to first matching section, not all. --align=COL start description of new entries at column COL. --calign=COL format second and subsequent description lines to start at column COL. --debug report what is being done. --delete delete existing entries for INFO-FILE from DIR-FILE; don't insert any new entries. --defsection=TEXT like --section, but only use TEXT if no sections are present in INFO-FILE (replacing "Miscellaneous"). --description=TEXT the description of the entry is TEXT; used with the --name option to become synonymous with the --entry option. --dir-file=NAME specify file name of Info directory file; equivalent to using the DIR-FILE argument. --dry-run same as --test. --entry=TEXT insert TEXT as an Info directory entry, overriding any corresponding entry from DIR-FILE. TEXT is written as an Info menu item line followed by zero or more extra lines starting with whitespace. If you specify more than one entry, all are added. If you don't specify any entries, they are determined from information in the Info file itself. --help display this help and exit. --info-dir=DIR same as --dir-file=DIR/dir. --info-file=FILE specify Info file to install in the directory; equivalent to using the INFO-FILE argument. --item=TEXT same as --entry=TEXT. --keep-old do not replace entries, or remove empty sections. --maxwidth, --max-width=COL wrap description at column COL. --menuentry=TEXT same as --name=TEXT. --name=TEXT the name of the entry is TEXT; used with --description to become synonymous with the --entry option. --no-indent do not format new entries in the DIR file. --quiet suppress warnings. --regex=R put this file's entries in all sections that match the regular expression R (ignoring case). --remove same as --delete. --remove-exactly only remove if the info file name matches exactly; suffixes such as .info and .gz are not ignored. --section=SEC put entries in section SEC of the directory. If you specify more than one section, all the entries are added in each of the sections. If you don't specify any sections, they are determined from information in the Info file itself; if nothing is available there, the --defsection value is used; if that is not specified, the final default is "Miscellaneous". --section R SEC equivalent to --regex=R --section=SEC --add-once. --silent suppress warnings. --test suppress updating of DIR-FILE. --version display version information and exit.
