On a 2.5 Solaris system, 'awk' and 'oawk' are hardlinks to the same binary
program, and are "old awk".  That Solaris's 'nawk' is a separate binary,
where the name designates "new awk", which adds features supporting larger
scripts:

 - The ability to define functions;
 - Execute Unix commands from a script;
 - Process the results of Unix commands;
 - Process command line arguments more gracefully;
 - Work more easily with multiple input streams.

In AIX, 'awk' and 'nawk' are hardlinks to the same binary program, which can
behave as one or the other by virtue of detected invocation name.
