The font contains a single character: the Begriffsschrift quantifier (in several sizes), as used to set the Begriffsschrift (concept notation) of Frege. The font is not intended for end users; instead it is expected that it will be used by other packages which implement the Begriffsschrift. An (unofficial) modified version of Josh Parsons' begriff is included as an example of implementation.
