  25 .LP
  26 The \fBelf32_checksum()\fR function returns a simple checksum of selected
  27 sections of the image identified by \fIelf\fR. The value is typically used as
  28 the \fB\&.dynamic\fR tag \fBDT_CHECKSUM\fR, recorded in dynamic executables and
  29 shared objects.
  30 .sp
  31 .LP
  32 Selected sections of the image are used to calcluate the checksum in order that
  33 its value is not affected by utilities such as \fBstrip\fR(1).
  34 .sp
  35 .LP
  36 For the 64\(mibit class, replace 32 with 64 as appropriate.
