addindex – Add index entries to LaTeX document

Ad­din­dex is C/Lex pro­gram to add in­dex en­tries to a LaTeX doc­u­ment. You start with a ‘names database’, which looks like the strings sec­tion of a BibTeX database; addin­dex scans your LaTeX file for strings in the database, and adds \in­dex com­mands for each match.
