NAME

       install-info - update info/dir entries

SYNOPSIS

       install-info [OPTION]... [INFO-FILE [DIR-FILE]]

DESCRIPTION

       Install or delete dir entries from INFO-FILE in the Info directory file DIR-FILE.

OPTIONS

       --delete
	      delete existing entries for INFO-FILE from DIR-FILE; don't insert any new entries.

       --dir-file=NAME
	      specify file name of Info directory file.  This is equivalent to using the DIR-FILE argument.

       --entry=TEXT
	      insert  TEXT as an Info directory entry.	TEXT should have the form of an Info menu item line plus zero or more extra lines starting
	      with whitespace.	If you specify more than one entry, they are all 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-file=FILE
	      specify Info file to install in the directory.  This is equivalent to using the INFO-FILE argument.

       --info-dir=DIR
	      same as --dir-file=DIR/dir.

       --item=TEXT
	      same as --entry TEXT.  An Info directory entry is actually a menu item.

       --quiet
	      suppress warnings.

       --remove
	      same as --delete.

       --section=SEC
	      put this file's 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.

       --version
	      display version information and exit.
