Remote server setup and configuration
Real world example

ir.exe installed onto every server via svn+teamcity
consts = “dns = 'ec2-127.0.0.1.amazon.com‘; file = ‘app.config’” command = “contents = System::IO::File.read_all_text(file); " + "contents = contents.replace(‘$(MACHINE_DNS)', dns); " + "System::IO::File.write_all_text(file, contents)"ir.exe -e ”#{consts}” -e ”#{command}”

Ruby as a scripting language

require 'win32ole'excel = WIN32OLE.new("excel.application")excel['Visible'] = true#Create a new sheetworkbook = excel.Workbooks.Addexcel.Range("a1")['Value'] = 3excel.Range("a2")['Value'] = 2excel.Range("a3")['Value'] = 1excel.Range("a1:a3").Select# Add a chartexcelchart = workbook.Charts.AddXL3D_COLUMN_CHART_TYPE = -4100excelchart['Type'] = XL3D_COLUMN_CHART_TYPE
Built-in to IronRuby & Excel
