libtext-bibtex-perl 0.88-3build1 (amd64 binary) in ubuntu focal

 The Text::BibTeX module provides functions to read, parse and write bibTeX
 files using perl.
 .
 The package provides two fundamental modules for processing BibTeX files
 (Text::BibTeX::File and Text::BibTeX::Entry).
 .
 In addition, the Text::BibTeX module provides a number of
 miscellaneous functions that are useful in processing BibTeX data
 (especially the kind that comes from bibliographies as defined by BibTeX
 0.99, rather than generic database files).
