bundle instructions for ifmapper

[faried]

Someone asked for help installing it, and I came up with the steps to use bundle to install and run it its own directory:

Install the required system packages:

sudo apt install libfox-1.6-dev ruby-dev libxrandr-dev ri bundler ruby

Create a directory for ifmapper:

mkdir -p ~/ifmapper
cd ~/ifmapper

Create a Gemfile with

source 'https://rubygems.org'
gem 'ifmapper'

Install everything inside the directory:

bundle config set --local path 'vendor/bundle'
bundle install

Run it:

bundle exec IFMapper
