   (description
    "Gawk is an implementation of Awk, a specialised programming language
for the easy manipulation of formatted text, such as tables of data. The GNU
implementation of Awk features a number of extensions beyond the traditional
implementations, making writing powerful text manipulation scripts a simple
task compared to writing similar programs in C.")
