Wolfgang Denk74de7ae2009-04-01 23:34:12 +02009 * The "source" command allows to define "script images", i. e. files
10 * that contain command sequences that can be executed by the command
11 * interpreter. It returns the exit status of the last command
12 * executed from the script. This is very similar to running a shell
13 * script in a UNIX shell, hence the name for the command.
