This utility returns sunrise and availability data for Handshake names.

1. Download the binary for your OS.
2. Move it somewhere on your $PATH, like this: sude mv namegrind-darwin-x64 /usr/local/bin/namegrind. You can replace namegrind-darwin-x64 with the filename and location of the binary you downloaded.

First, create an input file. The input file is simply a newline-delimited list of names, like this:

name1.
name2.
name3.

Then, run namegrind <infile>, where <infile> is replaced with the location of the input file you created above.

You'll see output that looks like this:

honk,15120,13,false
beep,17136,15,false
test,6048,4,false
farb,38304,36,false
1and1,49392,47,true
facebook,32256,30,true

These fields correspond to <name>,<available height>,<available week>,<reserved>. The output can be redirected to a CSV file for easy import into other programs.
