+% replacing each with a single hyphen ``|-|'',
+% use \cs{FilenameSimplify}:
+% \begin{sourceverb}
+% \FilenameSimplify*{-in-}
+% \FilenameSimplify*{A-}
+% \end{sourceverb}
+% The first example removes the word ''in'' in the middle of a filename,
+% and the second example removes ``A'' at the start of the filename.
+% The star forces the arguments to be detokenized, which is required for
+% a plain-text comparison.
+% (The unstarred form is used for a token-sensitive comparison, which is
+% seldom required by the user.)

+% Low-level macros such as \cs{begingroup} will cause problems when
+% nullfied.  Many macros such as \cs{textbf} are already nullfied.
+% \pkg{lwarp} also already nullifies built-in symbol and \pkg{textcomp} macros,

+% \pkg{xfakebold} is patched for use by \pkg{lwarp},
+% and additional underlying support is found in the \pkg{lwarp} core.
+%
+% Note that the print version resets to unbold at each page break,
+% \trouble[page breaks]{xfakebold=\pkg{xfakebold}}
+% whereas the \HTML\ version maintains the bold state until it is undone.
