+Epkg itself is not a package manager.

+Getting a local copy:

+git submodule update
address@hidden example
+
+Some submodule may be missing.  In this case Git will prompt for a GitHub user
+name and password.  To skip it press a @key{Return} key.
+
+You could get a Epkg package list by invoking @code{epkg-list-packages} in
+Emacs.")
