 Both forms read the files specified on the command line, and write a tag
-table (defaults: `\|TAGS\|' for \fBetags\fP, `\|tags\|' for
+table (defaults: \fBTAGS\fP for \fBetags\fP, \fBtags\fP for
 \fBctags\fP) in the current working directory.
 Files specified with relative file names will be recorded in the tag
 table with file names relative to the directory where the tag table
 resides.  Files specified with absolute file names will be recorded
 with absolute file names.
 The programs recognize the language used in an input file based on its
-file name and contents.  The --language switch can be used to force
+file name and contents.  The \fB\-\-language\fP switch can be used to force
 parsing of the file names following the switch according to the given
 language, overriding guesses based on filename extensions.
