Can't commit?

[Brenden Towey]

Hi all,

I have a bunch of files that I added to a brand new repository.  They 
all show as status ? with hg status:

$ hg status | grep build.xml
? build\build.xml

I tried to check these new files in, to create a baseline before any 
changes are made.  However, I get this:

$ hg commit
nothing changed

I have no idea how to fix this.  "Commit" is the only command or option 
I can find mentioned in the manuals.  I'm really at a loss how I'm 
supposed to commit a new file.  Any ideas how I'm supposed to do this?
