+An even simpler plumb patch
+===========================
+The differences of this patch to the simple, flexible plumb patch:
+
+* The code for retrieving and setting the current working directory and
executing is the
+ same as newterm, if patching with newterm it is suggested to keep the same
function, hence
+ no global variables and initialization, and current selection of plumb.
+* Double-fork execution of the plumber program, while this may have no benefit
with programs
+ that only launch in CLI, this may interfere with the swallow patch if
launching GUI programs.
+* No arguments are passed to the plumber program, only the plumber program
name is accepted.
+* The plumb function can be passed to the mouse shortcuts in `config.h`,
+ instead of being hard-coded.
