+<module name="BaseUnix">
+<short>Basic unix functionality</short>
+<descr>
+<p>
+The <file>BaseUnix</file> unit was implemented by Marco Van de Voort.
+It contains basic unix functionality. It supersedes the Linux unit of
+version 1.0.X of the compiler, but does not implement all functionality of
+the linux unit. 
+</p>
+<p>
+People that have code which heavily uses the old <file>Linux</file> unit,
+can simply change <file>linux</file> by <file>oldlinux</file> in the
+<var>uses</var> clause of their projects, but they should really consider
+moving to the <file>Unix</var> and <var>BaseUnix</var> units.
+</p>
+<p>
+For porting FPC to new unix-like platforms, it should be sufficient to
+implement the functionality in this unit for the new platform.
