# In Rubymine, do File -> Create Command-line Launcher
#  -- name it "mine", put in /usr/local/bin
#
# Also, create executable /usr/local/bin/firefox_to_mine with:
#    #!/usr/bin/ruby
#    url = ARGV.first
#    if url =~ /^mine\:([^\?]+)\?(.*)$/
#      `mine --line #{$2} #{$1}`
#    else
#      abort "Invalid parameter: #{url.inspect}"
#    end
#
# In Firefox: register a new protocol handler:
#  --about:config
#  --right-click -> New -> Boolean
#    name: network.protocol-handler.expose.mine
#    value: false
#
# Then, when you get an exception and click on one of the links, choose
# /usr/local/bin/firefox_to_mine as the handler.
