list iteration?

[Mike]

I have read in the manual where you can define a variable

var = ( a : b : c)

and have the var iterated like a list in some shell command.


command::
        "/bin/some/program $(var)"

At run-time how do you add something to the list such that
at the end it can be iterated over?

groups:
        any::
                var = (a : b : c)

editfiles:
        any::
                { /etc/hosts
                        HashCommentLinesMatching "127.0.0.1"
                        var = ( $(var) : $(host) )
                }

shellcommands:
        changelog::
                "cat $(var) >> /ChangeLog"
