View source for Extend.conf

Inside the scripts directory, there is a file present which is called <code>extend.conf</code>. This file was introduced in LFScript 4, to seperate BLFS specific instructions from the main executable.

The file is sourced at the start of each package build.

== Additional environment variables ==
=== BLFS ===
At the top of the file, additional environment variables are defined and exported. Among these are <code>XORG_PREFIX</code>, <code>XORG_CONFIG</code>, <code>KDE_PREFIX</code> and more. These variables are used throughout BLFS, to make the build more dynamic.

=== Build flags ===
If you want to set additional environment variables to be used during the build of '''all''' packages (like build flags), you should specify them in <code>extend.conf</code> too.

Starting with LFScript 4r21, the '''MAKEFLAGS''' variable is set by default, to ensure that all CPU cores are utilised during the build of your system. Setting the variable again in <code>extend.conf</code> will override this behaviour.

== BLFS Bootscripts ==
<code>extend.conf</code> contains a custom shell function called <code>includeBootscript</code>. This function takes one argument; The name of a BLFS Bootscript which needs to be installed.

This function makes it possible to install a bootscript using a single command in the package script. For example, in <code>alsa-utils</code> the bootscript is installed with:

<pre>includeBootscript alsa</pre>

Scripts requiring a BLFS Bootscript must have the bootscripts source in their [[WGETLIST | Script layout]].

== Mate ==
A more recent addition to <code>extend.conf</code> is the <code>convertToMate</code> function. This function adjusts source code designed for Gnome, so that it can use Mate in stead.

This function is still in development and may not work properly.
