This is the 6th release of X Window System software from the X Consortium.<tt> </tt>
|
||
|
|
X is a network-transparent window system which runs
|
||
|
|
on a wide range of computing and graphics machines.<tt> </tt>
|
||
|
|
<p>
|
||
|
|
The X Consortium is an independent, not-for-profit corporation,
|
||
|
|
the successor to the MIT X Consortium, which was part of the MIT
|
||
|
|
Laboratory for Computer Science.<tt> </tt>
|
||
|
|
See the <i>XConsortium</i> manual page for details.<tt> </tt>

<a name="toc3"> </a>
|

</h2>
|
||
|
|
<p>
|
||
|
|
|
||
|
|
There are two parts to Release 6: X Consortium software and
|
||
|
|
documentation, and user-contributed software and documentation.<tt> </tt>
|
||
|
|
The X Consortium part contains the following:
|
||
|
|
<dl>
|
||
|
|
<dt><b>X Consortium Standards</b><dd>
|
||
|
|
The X Consortium produces standards: documents which define
|
||
|
|
network protocols, programming interfaces, and other aspects of
|
||
|
|
the X environment. See the <i>XStandards</i> manual page for a
|
||
|
|
list of standards.<tt> </tt>
|
||
|
|
<dt><b>Sample Implementations</b><dd>
|
||
|
|
For most of our standards, we provide <i>sample</i> implementations
|
||
|
|
to demonstrate proof of concept. These are not <i>reference</i>
|
||
|
|
implementations; the written specifications define the standards.<tt> </tt>
|
||
|
|
<dt><b>Fonts</b><dd>
|
||
|
|
<br>
|
||
|
|
A collection of bitmap and outline fonts are included in the
|
||
|
|
distribution, contributed by various individuals and companies.<tt> </tt>
|
||
|
|
<dt><b>Utility Libraries</b><dd>
|
||
|
|
A number of libraries, such as the <i>Athena Widget Set</i>, are
|
||
|
|
included. These are not standards, but are used in building
|
||
|
|
X Consortium applications and may be useful in building other applications.<tt> </tt>
|
||
|
|
<dt><b>Sample Programs</b><dd>
|
||
|
|
We also provide a number of application programs.<tt> </tt>
|
||
|
|
A few of these programs, such as <i>xdm</i>,
|
||
|
|
should be considered essential in almost all environments.<tt> </tt>
|
||
|
|
The rest of the applications carry no special status; they
|
||
|
|
are simply programs that have been developed and/or maintained
|
||
|
|
by X Consortium staff.<tt> </tt>
|
||
|
|
In some cases, you will find better substitutes for these
|
||
|
|
programs in the user-contributed part.<tt> </tt>
|
||
|
|
</dl>
|
||
|
|
<p>
|
||
|
|
The user-contributed part contains whatever people contribute.<tt> </tt>
|
||
|
|
You'll find a variety of software and documentation here:
|
||
|
|
programs, demos, games, libraries,
|
||
|
|
X server extensions, etc.<tt> </tt>

The first thing you may notice is that you can't find anything.<tt> </tt>

The source tree has undergone a major reorganization since R5.<tt> </tt>
|

The top-level directory has been renamed from <b>mit/</b> to <b>xc/</b>.<tt> </tt>
|

|

<p>
|

|

|

|
|
Some of the specifications define some behavior as
|
||
|
|
implementation-dependent.<tt> </tt>
|
||
|
|
Implementations of X Consortium standards need to document how those
|

|
|
parameters are implemented; this section does so.<tt> </tt>
|
||
|
|
<dl>
|
||
|
|
<dt>XFILESEARCHPATH default<dd>
|
||
|
|
This default can be set at build time by setting the <i>imake</i> variables
|
||
|
|
XFileSearchPathDefault, XAppLoadDir, XFileSearchPathBase, and
|
||
|
|
ProjectRoot in <b>site.def</b>. See <b>xc/config/cf/Project.tmpl</b>
|
||
|
|
for how they are used.<tt> </tt>

<dt><dd><p>

<dt>XUSERFILESEARCHPATH default<dd>

If the environment variable XAPPLRESDIR is defined, the default value

of XUSERFILESEARCHPATH has the following components:
