+        help
+          The linux kernel is a kind of self-extracting executable.
+          Several compression algorithms are available, which differ
+          in efficiency, compression and decompression speed.
+          Compression speed is only relevant when building a kernel.
+          Decompression speed is relevant at each boot.
+
+          If you have any problems with bzip2 or lzma compressed
+          kernels, mail me (Alain Knaff) <alain@knaff.lu>. (An older
+          version of this functionality (bzip2 only), for 2.4, was
+          supplied by Christian Ludwig)
+
+          High compression options are mostly useful for users, who
+          are low on disk space (embedded systems), but for whom ram
+          size matters less.

+          The old and tried gzip compression. Its compression ratio is
+          the poorest among the 3 choices; however its speed (both
+          compression and decompression) is the fastest.
+
+config KERNEL_BZIP2
+        bool "Bzip2"
+        depends on HAVE_KERNEL_BZIP2
+        help
+          Its compression ratio and speed is intermediate.
+          Decompression speed is slowest among the three.  The kernel
+          size is about 10% smaller with bzip2, in comparison to gzip.
+          Bzip2 uses a large amount of memory. For modern kernels you
+          will need at least 8MB RAM or more for booting.
+
+config KERNEL_LZMA
+        bool "LZMA"
+        depends on HAVE_KERNEL_LZMA
+        help
+          The most recent compression algorithm.
+          Its ratio is best, decompression speed is between the other
+          two. Compression is slowest.  The kernel size is about 33%
+          smaller with LZMA in comparison to gzip.
