When I was working at my first ext2 driver implementation, I found myself short of
|
|
documentation on the subject. It wasn't so much the information not being available
|
|
as of it not being available all in one place.
|
|
<p>
|
|
This project tries to fix this, by bringing in one single place all the useful
|
|
information in one easy to understand package. I try to not tie the documentation
|
|
to any particular operating system, so that it may be useful to the widest audience.
