// Class libo4 is a C++ wrapper around the libo4 porting library. It handles
// basic stuff like dynamic loading, library initialization etc.
// The libo4 porting library is a set of functions that bridge from the AIX
// runtime environment on OS/400 (aka PASE layer) into native OS/400
// functionality (aka ILE layer) to close some functional gaps that exist in
// the PASE layer.
