All,

I have now had several people make a project suggestion as a means of
assembling the various pieces of a large task. Hans has described the
procedure below. I would like to give this a try, but I have a few
questions before restructuring my documents.

1. Do you recommend that I pursue this technique? I think yes?

2. Here's how I like to structure my project directories;

f:\book
f:\book\chap1
f:\book\chap2
f:\book\chap3
f:\book\chap4
f:\book\chap5
f:\book\chap6
f:\book\chap7
f:\book\chap8
f:\book\chap9
f:\book\chap10

The directory f:\book contains my master document, master.tex. Each of the
directories f:\book\chapi contains a file called chapi.tex and all of the
files needed to construct that file, *.eps, *.pdf, *.m (matlab files), *.mp
(Metapost files), etc. Each directory has a SIGNIFICANT number of files.
This is how I like to work, because chunking everything into one directory
would quickly become unmanageable, at least for me.

Now, knowing these parameters, am I still a candidate to use this
project--product approach?
