-#' Import and Manage BibTeX and BibLaTeX references with RefManageR
-#'
-#' RefManageR provides tools for importing and working with
-#' bibliographic references.  It greatly enhances the bibentry class by
-#' providing a class BibEntry which stores BibTeX and BibLaTeX references,
-#' supports UTF-8 encoding, and can be easily searched by any field, by date
-#' ranges, and by various formats for name lists (author by last names,
-#' translator by full names, etc.). Entries can be updated, combined, sorted, printed
-#' in a number of styles, and exported. BibTeX and BibLaTeX .bib files can be
-#' read into R and converted to BibEntry objects.  Interfaces to NCBI's
-#' Entrez, CrossRef, and Zotero are provided for importing references and
-#' references can be created from locally stored PDFs using Poppler.  Includes
-#' functions for citing and generating a bibliography with hyperlinks for
-#' documents prepared with RMarkdown or RHTML.
