It can handle any BibTeX style (even those producing multiple bibliographies), use additional fields (like "abstract", "url", and "ps") to insert Web links, replace cross-references with links, sort on various fields, process simple (La)TeX macros, identify syntax errors in BibTeX files, and filter BibTeX entries based on a given criterion.
SiSU (Structured information, Serialized Units) is a lightweight markup based, text structuring and publishing framework (that features granular search). With minimal markup of a plaintext file, it produces: plain-text, HTML, XHTML, XML, ODF, LaTeX, PDF, and populates an SQL database at an object/paragraph level for granular searches. Prepare documents using your text editor of choice, then use SiSU to generate the desired output formats. SiSU is controlled from the command line.
