* The "source" command allows to define "script images", i. e. files
|
|
* that contain command sequences that can be executed by the command
|
|
* interpreter. It returns the exit status of the last command
|
|
* executed from the script. This is very similar to running a shell
|
|
* script in a UNIX shell, hence the name for the command.
