jq - 1.5+dfsg-2+b1 main

jq is like sed for JSON data – you can use it to slice
and filter and map and transform structured data with
the same ease that sed, awk, grep and friends let you
play with text.
.
It is written in portable C, and it has minimal runtime
dependencies.
.
jq can mangle the data format that you have into the
one that you want with very little effort, and the
program to do so is often shorter and simpler than
you’d expect.
