+#   make CROSS=powerpc-linux- BB_SRC_DIR=$HOME/busybox PREFIX=/mnt/app
+
+# If you want to add some simple compiler switches (like -march=i686),
+# especially from the command line, use this instead of CFLAGS directly.
+# For optimization overrides, it's better still to set OPTIMIZATION.

+# This enables compiling with dmalloc ( http://dmalloc.com/ )

+# detector.  To enable dmalloc, before running busybox you will
+# want to first set up your environment.
+# eg: `export DMALLOC_OPTIONS=debug=0x34f47d83,inter=100,log=logfile`
+# The debug= value is generated using the following command
+# dmalloc -p log-stats -p log-non-free -p log-bad-space -p log-elapsed-time \
+#      -p check-fence -p check-heap -p check-lists -p check-blank \
+#      -p check-funcs -p realloc-copy -p allow-free-null
