To save disk space, Emacs is built with the idea that you will execute
it from the same place in the file system where you built it. As the
/usr/local/ subtree does not exist on most MSDOG systems, the
-executables are placed in /emacs/bin/.
+executables might be placed in /emacs/bin/, for instance, in which
+case there should also be /emacs/lisp, /emacs/info and /emacs/etc
+directories. In general, with the default path handling, the etc/,
+info/ and lisp/ directories are expected to exist in ../ relative to
+the directory containing the executing binary. This behaviour can be
+overridden by setting the HOME environment variable to the directory
+containing lisp/ etc.
MSDOG is a not a multitasking operating system, so Emacs features such
as asynchronous subprocesses that depend on multitasking will not
