description="
Pattern scanning and processing language.

The awk utility interprets a special-purpose programming language
that makes it possible to handle simple data-reformatting jobs
with just a few lines of code.  It is a free version of 'awk'.

GNU awk implements the AWK utility which is part of
IEEE Std 1003.1 Shell and Utilities (XCU).
