examines one or more scripts and produces a .SH file that, when run under sh,
will produce the original script.
The .SH script so produced has two sections containing code destined for
The first section has variable substitutions performed on it (taking values
from config.sh), while the second section does not.
MakeSH does not know which variables you want to have substituted, so it puts
the whole script into the second section.
It's up to you to insert any variable substitutions in the first section
for any values you want from config.sh.
You should run
from within your top-level directory and use the relative path to the file
as an argument, so that the "Extracting ..." line printed while running
the produced .SH file later on will give that same path.
