BitBake Shell
IDEAS:
* list defined tasks per package
* list classes
* toggle force
* command to reparse just one (or more) bbfile(s)
* automatic check if reparsing is necessary (inotify?)
* frontend for bb file manipulation
* more shell-like features:
- output control, i.e. pipe output into grep, sort, etc.
- job control, i.e. bring running commands into background and foreground
* start parsing in background right after startup
* ncurses interface
PROBLEMS:
* force doesn't always work
* readline completion for commands with more than one parameters
