+       "Biblib provides a simple, standalone Python 3 package for parsing
+BibTeX bibliographic databases, as well as algorithms for manipulating BibTeX
+entries in BibTeX-y ways.  Biblib's parser is derived directly from the WEB
+source code for BibTeX and hence (barring bugs in translation) should be fully
+compatible with BibTeX's own parser.")
+      ;; N.B. It seems the parser was translated from WEB by hand: this
+      ;; package does not contain any generated files.
