[p4] PowerShell Integration

[Shawn Hladky]

You may want to wait a bit before using P4.Net.  I have a large set of
changes queued up, and plan on submitting in the next couple of days.  It
will include quite a bit of documentation, a new sample application, a
couple bug fixes, and minor refactoring.

As for PowerShell, It looks really cool, but I haven't dug much into how
cmdlets work.  My guess is that a generic integration would be pretty easy
to pull off building on P4.Net... something like:

p4-run changes -s pending ...

So the arguments would be identical to the std cli, but it would return a
rich object providing tagged output as a list of dictionaries.  In P4.Net, I
call it a P4RecordSet.  I imagine accessing dictionary elements by key in
PowerShell is straight-forward.

This is similar to the approach I have in the MSBuild custom task sample.
Rather than using the Ant/Nant paradigm, where there are separate tasks for
each Perforce activity (P4Sync, P4Label, P4Edit, etc.), I have a single task
to run any p4 command.  Then I abuse MSBuild's ItemGroups and metadata to
provide access to all the tagged output for use later in the script.  In my
next submit, I'll have a sample MSBuild script that demonstrates the
"working offline" technique completely from MSBuild.  Except for some
strange-looking MSBuild transformations, it's quite simple, and you couldn't
accomplish anything close to that with the Ant/Nant paradigm.
