+.LP
+The \fBelf32_checksum()\fR function returns a simple checksum of selected
+sections of the image identified by \fIelf\fR. The value is typically used as
+the \fB\&.dynamic\fR tag \fBDT_CHECKSUM\fR, recorded in dynamic executables and
+shared objects.
+.sp
+.LP
+Selected sections of the image are used to calcluate the checksum in order that
+its value is not affected by utilities such as \fBstrip\fR(1).
