-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.
