+You can disregard these if they're in the form shown,
+where the ignored AGL name contains four hexadecimal digits
+.IR XXXX .
+.
+The Adobe Glyph List (AGL) has its own names for glyphs;
+they are often
+different from
+.IR groff 's
+special character names.
+.
+.I \%afmtodit
+is constructing a mapping from
+.I groff
+special character names to AGL names;
+this can be a one-to-one or many-to-one mapping,
+but one-to-many will not work,
+so
+.I \%afmtodit
+discards the excess mappings.
+.
+For example,
+if
+.I x
+is
+.BR *D ,
+.I y
+is
+.BR \%Delta ,
+and
+.I z
+is
+.BR uni0394 ,
+.I \%afmtodit
+is telling you that the
+.I groff
+font description that it is writing cannot map the
+.I groff
+special character
+.B \[rs][*D]
+to AGL glyphs
+.B \%Delta
+and
+.B uni0394
+at the same time.
+.
+.
+.IP
+If you get a message like this but are unhappy with which mapping is
+ignored,
+a remedy is to craft an alternative
+.I map-file
+and re-run
+.I \%afmtodit
+using it.
