#
# This script will:
# 1) install system dependencies based on the Linux flavor (~Debian or Fedora)
# 2) install a custom-compiled openssl into $MYUSR_PREFIX (see config below)
# 3) install rvm and ruby
# 4) install mastercoin-wallet
#
# :NOTE: Successive runs of the this script will upgrade and/or re-install the
# packages it installs.  If this script fails at anytime (due to failed
# dependencies, etc) it is OK to run the script again.
