Recompiling the Kernel?

["Marc Sherman" <msherman@myrealbox.com>]

Is there a Debian-specific howto or man page for recompiling
the kernel?  I apt-got the kernel-source-2.2.14 and 
kernel-package packages, but after installation, /usr/src
did not have a directory containing the source for kernel
2.2.14 - just a single file, whose extension was .bz2.  What
do I do with that file to get a source diectory?

Thanks,
