+.B Atom USE defauts
+Beginning with \fBEAPI 4\fR, \fBUSE\fR dependencies may specify default
+assumptions about values for flags that may or may not be missing from
+the \fBIUSE\fR of the matched package. Such defaults are specified by
+immediately following a flag with either \fB(+)\fR or \fB(\-)\fR. Use
+\fB(+)\fR to behave as if a missing flag is present and enabled, or
+\fB(\-)\fR to behave as if it is present and disabled:
