+<title>Building GStreamer on UNIX</title>
+
+  <!-- this has been borrowed from the glib docs -->
+  <para>
+    On UNIX, GStreamer uses the standard GNU build system,
+    using <application>autoconf</application> for package
+    configuration and resolving portability issues,
+    <application>automake</application> for building makefiles
+    that comply with the GNU Coding Standards, and
+    <application>libtool</application> for building shared
+    libraries on multiple platforms.  The normal sequence for
+    compiling and installing the GStreamer library is thus:
+
+    <literallayout>
+      <userinput>./configure</userinput>
+      <userinput>make</userinput>
+      <userinput>make install</userinput>
+    </literallayout>
+  </para>
+
+  <para>
+    The standard options provided by <application>GNU
+    autoconf</application> may be passed to the
+    <command>configure</command> script.  Please see the
+    <application>autoconf</application> documentation or run
+    <command>./configure --help</command> for information about
+    the standard options.
+  </para>
+
+  <para>
+    In addition there are several option to activate or deactivate features.
+    E.g. passing <option>--disable-gst-debug</option> to <command>configure</command>
+    will turn the debugging subsystem into non-functional stub and remove all
+    macro based invokations from within the library (and anything compiled
+    against the library afterwards)
+  </para>
+  <para>
+    If library size matters and one builds in a controlled environment, its also
+    possible to totaly remove sybsystem code. This is intetionally not offered
+    as a configure option as it causes an ABI break. Code build against a
+    version of GStreamer without these modifications needs to be recompiled.
+
+    <literallayout>
+      <userinput>make CFLAGS="-DGST_REMOVE_DEPRECATED -DGST_REMOVE_DISABLED"</userinput>
+    </literallayout>
+    
+    <itemizedlist>
+      <listitem>
+        <para>
+          <symbol>GST_REMOVE_DEPRECATED</symbol> - Omit deprecated functions
+          from the library.
+        </para>
+      </listitem>
+      <listitem>
+        <para>
+          <symbol>GST_REMOVE_DISABLED</symbol> - Omit stubs for disabled
+          subsytems from the library.
+        </para>
+      </listitem>

+<title>Building GStreamer Applications</title>
+
+<para>
+Applications and libraries can use <command>pkg-config</command> to get all the
+needed compiler and linker flags building against GStreamer. Please note that
+GStreamer is split into several libraries itself. 
+<command>pkg-config --list-all | grep gstreamer</command> will list the
+available libraries.
