-# 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 \
