jsroute/README

   1 The jsroute sub-project allows us to use Google Maps from the command
   2 line. To do this, we require the env-js Javascript library. A remote
   3 reference, called a "submodule,"[1] has been created in the
   4 census-tools repository and points to env-js. To initialize/update it,
   5 run,
   6
   7   git submodule init
   8   git submodule update
   9
  10 Those two commands will initialize the submodule, and check it out
  11 within the lib/env-js directory. Now that env-js is present, you'll
  12 need to build it. There are some prerequisites for this; in
  13 particular, a Java runtime[2] and the Ant[3] build tool. If you are
  14 running Linux, I promise that both of these are available through your
  15 package manager.
  16
  17 With the prerequisites installed, simply run 'make env-js' from within
  18 the 'lib' directory. This will change into the env-js directory, and
  19 run 'ant concat' which builds the library. With that complete, you can
  20 use jsroute.
  21
  22 Just run ./jsroute from within this directory to display its usage.
