 The kconfig language is a hacked version, vampirised from the Linux kernel
 (http://www.kernel.org/), and (heavily) adapted to my needs.
 
+The list of the most notable changes (at least the ones I remember) follows:
+- the CONFIG_ prefix has been replaced with CT_
+- a leading | in prompts is skipped, and subsequent leading spaces are not
+  trimmed
+- otherwise leading spaces are silently trimmed
+
 The kconfig parsers (conf and mconf) are not installed pre-built, but as
 source files. Thus you can have the directory where crosstool-NG is installed,
 exported (via NFS or whatever) and have clients with different architectures
