Keith,
Welcome to the forums.
Are you saying that the procedures require you to check out
all the application or site code in addition to your RH source
because RH may change some of that external code? To my knowledge,
RH source is not connected to anything else in a way that it will
make automatic changes to anything outside the project. I don't
know about an official list, but I have seen (by using the Tortoise
client for both CVS and SVN) that if you make edits to RH source
files, those files change of course, and then I believe the .cpd
file is about the only other thing that changes.
You could try downloading and installing Tortoise if it works
for the version control system you use. Tortoise shows graphically
within Windows Explorer which files have changed since the last
time you checked a directory into the repository. If you change
nothing besides your RH source, Tortoise would plainly show that RH
isn't touching the application or site's code.
Hope this helps,
Ben
