With this interface, you can execute other non-Ceilidh commands or even log out at any point. When you resume, the course, unit and exercise will remain set just as when you last issued a Ceilidh command (although you may choose to execute "status" to check the settings). This interface will be particularly useful for the "pr2" course, in which you need to perform all compilations yourself.
With this interface there is never any need to use "q" to quit the various levels of Ceilidh.
At any time, type
commands
to remind yourself of the commands currently available. The command
status
shows the currently set course, unit and exercise.
Typing
~ceilidh/bin.cli/set.env
will clear out the currently set values for course, unit and exercise. You will then need to use "set.cse", "set.unit" etc to reset them to the values you require.
