  27 // The purpose of this code is to dynamically load the libperfstat library
  28 // instead of statically linking against it. The libperfstat library is an
  29 // AIX-specific library which only exists on AIX, not on PASE. If I want to
  30 // share binaries between AIX and PASE, I cannot directly link against libperfstat.so.
