 The current {{{kmk}}} code contains the following changes from [wiki:'GNU make']:

+ * Explicit multi-target rules, e.i. explicit make rules that output more than one file.
+ * Prepend assignment operator, {{{<=}}}.
  * It contains bugfixes for several bugs in the Windows and OS/2 ports, most importantly path case mixups, broken shell invocation, and abspath.
- * It has several performance improvements with respect to the kind of work [wiki:kBuild kBuild] puts make thru. Most notably, keeping name and value lengths for variables and thereby skipping a lot of {{{strlen()}}} and being able to use {{{memcpy()}}} instead of {{{strcpy()}}}, and the variable expansion optimization ({{{+=}}}). The latter was a major issue with the way [wiki:kBuild kBuild] is scripted.

    * kmk_builtin_rmdir
-   On the todo list is:
-   * kmk_builtin_mv
-   * ...
+   * kmk_builtin_printf
  * A new argument {{{--priority <1..5>}}} which sets the priority of the [wiki:kmk] process. 1 is idle time, 3 is normal, and 5 is highest priority.
  * The special {{{.NOTPARALLEL}}} [wiki:goals goal] has been extended to be able to take a list of [wiki:goals] that must be executed without any parallel building going on. If no list is given, it will work like in vanilla [wiki:'GNU make'] which means the entire makefile will be executed without any parallel building. This extension is required to make the {{{-jN}}} argument useful in [wiki:kBuild].
