• Everybody should have received it from the mailing list

• Some Regular Expression code as an example to read the config. file (tonight labs, from 5pm to 7pm)

• How to test your assignment

  • Go on the field, and measure real life angle

  • Measure it on the paper, with any protractor

  • Take this example :
