bk-kernel-howto.txt: Description of kernel workflow under BitKeeper

bk-make-sum: Create summary of changesets in one repository and not
another, typically in preparation to be sent to an upstream maintainer.
Typical usage:
	cd my-updated-repo
	bk-make-sum ~/repo/original-repo
	mv /tmp/linus.txt ../original-repo.txt

bksend: Create readable text output containing summary of changes, GNU
patch of the changes, and BK metadata of changes (as needed for proper
importing into BitKeeper by an upstream maintainer).  This output is
suitable for emailing BitKeeper changes.  The recipient of this output
may pipe it directly to 'bk receive'.

bz64wrap: helper script. Uncompressed input is piped to this script,
which compresses its input, and then outputs the uu-/base64-encoded
version of the compressed input.

csets-to-patches: Produces a delta of two BK repositories, in the form
of individual files, each containing a single cset as a GNU patch.
Output is several files, each with the filename "/tmp/rev-$REV.patch"
Typical usage:
	cd my-updated-repo
	bk changes -L ~/repo/original-repo 2>&1 | \
		perl csets-to-patches

cset-to-linus: Produces a delta of two BK repositories, in the form of
changeset descriptions, with 'diffstat' output created for each
individual changset.
Typical usage:
	cd my-updated-repo
	bk changes -L ~/repo/original-repo 2>&1 | \
		perl cset-to-linus > summary.txt

unbz64wrap: Reverse an encoded, compressed data stream created by
bz64wrap into an uncompressed, typically text/plain output.
