I have been in conversation with a team who is looking to use a code metrics tool for which no integration exists with RTC.  The metrics tool people said they can build an integration if they can do the following (and I have tried to rephrase these in RTC terminology):

·         query SCM for updates to a particular project (ie what has changed in a project area for one, some of all streams associated with the project)
·         associate changes over a given period with specific developers (I interpret this in RTC terminology  identifying all changesets delivered by a specific user over a specific time period)
·         checkout a set of revisions as buildable packages (from the other info I have - this is grabbing specific versions of the code - I would usually do this against a named snapshot - which is pretty standard).

Are any of these types of query/command possible from the commandline? 

This is for RTC 4.x.

thanks
