#!/usr/bin/env bash

# This shell script will download the software required to build the ref
# guide using RVM (Ruby Version Manager), and then run the following
# under solr/solr-ref-guide: "ant clean build-site build-pdf".
#
# The following will be downloaded and installed into $HOME/.rvm/:
# RVM, Ruby, and Ruby gems jekyll, asciidoctor, jekyll-asciidoc, 
# and pygments.rb.
#
# The script expects to be run in the top-level project directory.
#
# RVM will attempt to verify the signature on downloaded RVM software if
# you have gpg or gpg2 installed.  If you do, as a one-time operation you
# must import two keys (substitute gpg2 below if you have it installed):
#
#    gpg --keyserver hkp://keys.gnupg.net --recv-keys \
#        409B6B1796C275462A1703113804BB82D39DC0E3     \
