Includes a C library called btparse and a perl library Text::BibTeX. Features include: robust, efficient lexical scanning and parsing of BibTeX files; excellent error detection, reporting, and recovery in the parser; full processing of BibTeX strings (macros expanded, whitespace collapsed, strings concatenated); handles all common entry types (@comment, @preamble, @string, and everything else) with ease, and gives you full access to the contents of all entry types; support for processing author names identically to BibTeX; preliminary support for imposing/enforcing a particular database structure.
