Publishing and processing scientific documents leads to an ever growing collection of
most commonly BibTeX-entries, which quickly becomes a mess when not properly organized.
This can be a tedious and time-consuming task when done by hand, and tends to be always out-of-date
nonetheless. Further there is the need to publish an entire BibTeX-bibliography as well as just a subset.
Numerous tools for keeping a tidy bibliography exist, which fulfill their intended purpose,
so do tools that care for exporting entire BibTeX-files to a range of different formats,
like HTML, XML and such.
Unfortunately these tools cannot be used to process only a subset and further are only suitable to
perform either management or conversion.
The intent for creating Bib2x was to have a tool with named features and at the same time
provide flexibility and extendibility.
Bib2x enables filtering on a set of bibliographic entries read from BibTeX databases and
allows entirely user-defined export to arbitrary file formats using
