my $USAGE = <<ENDUSAGE;
Remove \@tindex lines from files that were already present in previous
versions.
Usage: $0 [--old=EXT] FILE...
$0 --help
$0 --version
--help display this help and exit
--version print version and exit
--old=DIR find old files in DIR
The script performs two passes. In the first pass, Texinfo files from
DIR are scanned for \@tindex lines, and identifiers in them are
recorded. In a second pass, Texinfo files in the current directory
are scanned, and \@tindex lines for identifiers that were recorded in
the first pass are removed. Old file contents are saved in files
with extension ".orig". A list of modified files and removed \@tindex
identifiers is printed to stdout at the end.
