What is an applied patch in a Mercurial queue?

Question

The documentation is littered with mentions of "applied patches", i.e. in hg qfold, it says "Patches must not yet be applied."

How do I apply a patch, and how do I know when a patch is applied? This concept doesn't seem to appear in the output of hg qser or its --help.

Answer 1

Once I left the --help behind, I was able to find this:

hg qapplied
