-% \pkgname{repltext} relies on the \cs{pdfliteral} and

+% \pkgname{repltext} additionally needs a mechanism to escape
+% backslashes and parentheses in a string to make it usable as a PDF
+% string.  This is easy in pdf\LaTeX, which provides
+% \cs{pdfescapestring}.  Unfortunately, to my knowledge, no other
+% \TeX\ engine provides equivalent functionality.  Rather than write our
+% own function, we leverage \pkgname{hyperref}'s \cs{Hy@pstringdef},
+% which provides similar functionality.
