Beagle also allows users to write their own simple filters by using external programs. For example, one could use untex to extract text data from TeX files. To create these filters, users simply add information to the external-filters.xml file. Instructions and a sample config file can be found at external-filters.xml.sample file.

To obtain examples or to share your own external-filters.xml, check out the ExternalFiltersRepository.
