.TH NAMESPACE 4

.SH NAME
|

namespace \- structure of conventional file name space

.SH SYNOPSIS

none
|
|
.SH DESCRIPTION
|
|
After a user's profile has run, the file name space should adhere
|
|
to a number of conventions if the system is to behave normally.
|
|
This manual page documents those conventions by traversing the
|
|
file hierarchy and describing the points of interest.
|
|
It also serves as a guide to where things reside in the file system proper.
|
|
The traversal is far from exhaustive.
