BibTeX, biblatex and biber ⇒ Building a CV automatically with BibLaTeX

[beeper]

I am trying to use LaTeX, BibTeX, and BibLaTeX to automatically build a
CV from a bib file. This requires a number of new bib entry types (e.g.,
funding, classes, talks, etc.) and fields. I am having trouble finding a
way to add entries without hacking the biblatex.bst and biblatex.sty
files. Is it possible to add new entry types and fields without directly
editing the .bst and .sty files?
