Yes.

The colours will mess with that, as will grep - you have to escape any
regular expression metacharacters if you're piping Freshen
--no-colours through it.

For what you're doing, SVN Freshen/Scripts and the -p option will do
what you want. That also required some CheckDependencies fixes, so I
can't release it until there's a new Scripts out.

Not even that, it just shows *a* program higher up that is already
installed (or listed explicitly on the command line). Consider this
example:
A depends on B, and an older version is already installed.
B depends on C, and an older version is already installed installed.
C is not installed.
Here, you could get *either* A or B listed as introducing C, and it's
completely arbitrary which it will be.

It's (in effect) topologically sorted. Every program comes after all
of its dependencies, but positioning other than that is undefined.
There are many possible topological sorts for a given graph, so you
may get a drastically different order when you choose only part of it.
--unordered is in arbitrary order, with no dependencies listed.

Whichever one comes first will introduce it somewhere before itself,
listed as introduced by it if not already installed. Every other
program using it will see that it's already in the list and continue
happily along with the rest of its dependencies.
