Using Mercurial (hg), how to push just one file or one directory out?

Question

Using Mercurial, we can commit one file by using

hg commit file.rb

or 1 folder

hg commit foldername

But how can we push just 1 file or 1 folder out?

The whole project can be pushed using

hg push ssh://[email protected]//project/code/preliminary

but there seems to be no way to push out just 1 file or 1 folder?

I tried the following and they don't work:

hg push ssh://[email protected]//project/code/preliminary app/views/index.html.erb

or

hg push ssh://[email protected]//project/code/preliminary/app/views/index.html.erb

That's not really possible to do with Mercurial. The whole point of Mercurial (and Subversion and git and pretty much every version-control system since CVS) is that you deal with changesets; each commit is a set of changes to one or more files. push and pull only know about commits, not about each part of every commit.
