As one possible solution to this name conflict, I've folded my org-bibtex.el into the existing org-bibtex.el in the Org-mode core. The attached patch performs this integration adding the functionality in my version of org-bibtex.el into the Org-mode core. Does this seem like an appropriate addition? Thanks -- Eric (p.s. created with "git format-patch" and can be applied using "git am")
