# Already set upon entry: see "rules.mk".
# 
# Optionally set on entry:
# 
# 	$(shell-scripts)	source files, with the extension .sh,
# 				to turn into executable scripts.
# 
# 	$(cfg__posix_shell)	the program to use in "#!" lines
#				for shell scripts (default "/bin/sh")
# 
# This file creates executable programs from shell scripts.  These
# programs are created in the build directory and not installed.  (See
# "install-program.mk".)
#
# By default, shell-scripts is all files in the source directory with
# the extension "sh" and beginning with any of [a-zA-Z0-9].
#
# On `make all', the scripts are copied to the build directory,
# without the ".sh" extension, and chmoded to be executable by
# anyone.
#
# If the source file does not already have a first line beginning
# with "#!", then a line "#!/bin/sh" is added.
#
