+The
+.B \-convertargs
+switch directs
+.B repl
+to pass the arguments for
+.I type
+to
+.BR mhbuild .
+Both arguments are required;
+.I type
+must be non-empty while
+.I argstring
+can be empty, e.g., '' in a shell command line. The
+.B \-convertargs
+switch can be used multiple times.
+See the Convert Interface section of
+.IR mhbuild (1)
+for a description of the convert mechanism, and
+.I %docdir%/contrib/replaliases
+for examples of its use.
