| 23 | We have the following windows: | ||
| 24 | |||
| 25 | 1.) Main Window: Shows what we are ultimately building and how far we are. Includes status bar | ||
| 26 | 2.) Thread Activity Window: Shows one status line for every concurrent bitbake thread. | ||
| 27 | 3.) Command Line Window: Contains an interactive command line where you can interact w/ Bitbake. | ||
| 28 | |||
| 29 | Basic window layout is like that: | ||
