Subject: Added docs for search paths.
X-Git-Tag: V2.12.0~1539
X-Git-Url: https://git.sur5r.net/?a=commitdiff_plain;h=5afb710f9801ff697969e9e07a469e72356100f7;p=cc65

Added docs for search paths.
Removed builtin configs - It's too difficult to keep them up-to-date.

+<sect1>Builtin configurations<p>
 
-The "<tt/start/" attribute for the <tt/RAM/ memory area of the CBM systems is
-two less than the actual start of the basic RAM to account for the two bytes
-load address that is needed on disk and supplied by the startup code.
+The builtin configurations are part of the linker source. They are also
+distributed together with the machine specific binary packages (usually in the
+doc directory) and don't have a special format. So if you need a special
+configuration, it's a good idea to start with the builtin configuration for
+your system. In a first step, just replace <tt/-t target/ by <tt/-C
+configfile/. The go on and modify the config file to suit your needs.
