"""

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