// Search & replace patterns for conversion from refbase markup to PDF markup & entities. Note that there's currently no conversion of emdashes
// or markup for greek letters and super-/subscript (since I don't know how to print chars by code number or how to print Unicode chars directly).
// Search & replace patterns must be specified as perl-style regular expression and search patterns must include the leading & trailing slashes.
