This is useful when one has a database (in JSON form) to query using jq
input data.
% echo '{"a":1, "c":5}' > db.json
% echo '"c"'|./jq --argfile f /tmp/a '$f[.]'
5
% echo '"a"'|./jq --argfile f /tmp/a '$f[.]'
1
% echo '"b"'|./jq --argfile f /tmp/a '$f[.]'

Documentation
The jq website, manpages and some of the tests are generated from this
directory. The directory holds a Bonsai
website, and the manual is a YAML file in content/3.manual.
To build the documentation (including building the jq manpage), you'll need a working Ruby setup. The easiest way to get one is to install RVM and Ruby 1.9.3 like so:
\curl -L https://get.rvm.io | bash -s stable --ruby=1.9.3
After that finishes installing, you'll need to make sure RVM is on
your path by doing source $HOME/.rvm/scripts/rvm, or just opening a
new shell. See http://rvm.io for more info on RVM.
Once RVM is installed, you can install all the dependencies for jq's
documentation build by running this from the docs directory:
bundle install
When bundle manages to install the dependencies, rerun ./configure
in the jq root directory and then the Makefile will be able to
generate the jq manpage.
