A customer registered their program to be run automatically
under conditions not important to the story.
They found, however, that the program didn't work because
the program was written with an application framework that
looks for configuration files in the current directory,
but the system wasn't setting the current directory properly.
They couldn't change the directory in their program because
the code that looks for the configuration file is in the
framework, and it runs before any of their code does.
Oh, and I forgot to mention that
mention that the
FIZZBIN
environment
variable needs to be set to
KRONK,
except on Tuesdays,
in which case it needs to be
SHRONK.
Except at night.
Okay, maybe the customer's requirements weren't that weird,
but you get the idea.
You can't get the system to do all these things for you,
but you don't have to.
Write a helper program and register the helper with the system.
The helper program sets the current directory,
sets the FIZZBIN environment variable,
does all the fancy preliminary nonsense your precious
program requires,
and then launches the real program.
Bingo, your current directory, environment variable,
and favorite teddy bear are all set up waiting for you.
