+Essentially, a command shell is all about invoking commands---and
+everything that entails.  So understanding how Eshell invokes commands
+is the key to comprehending how it all works.

 @section Invocation
 
+Unlike regular system shells, Eshell never invokes kernel functions
+directly, such as @code{exec(3)}.  Instead, it uses the Lisp functions
+available in the Emacs Lisp library.  It does this by transforming the
+command you specify into a callable Lisp form.@footnote{To see the Lisp
+form that will be invoked, type: @samp{eshell-parse-command "echo
+hello"}}
+
+This transformation, from the string of text typed at the command
+prompt, to the ultimate invocation of either a Lisp function or external
+command, follows these steps:
+
+@enumerate
+@item Parse the command string into separate arguments.
