-# deblob-main - prepare a GNU Linux-libre tarball out of a non-libre
-# Linux tarball. It expects the Linux release (mver, say 3.0) as the
-# first argument, the gnu sub-release (extra) as the second optional
-# argument, and the patch release (sver, say .13) as an optional third
-# argument. mver and sver are pasted together to form kver.
-
-# linux-$kver.tar.bz2 and deblob-$mver must exist in the current
-# directory, and the line that sets kver and extra in deblob-$mver
-# must match mver and extra.
-
-# The resulting tarball is put in linux-libre-$kver-gnu$extra.tar.bz2.
-# An uncompressed xdelta that produces linux-libre-$kver-gnu$extra.tar
-# out of linux-$kver.tar is put in linux-libre-$kver-gnu$extra.xdelta.
-# This xdelta can be distributed to enable third parties to easily
-# reconstruct the binary tarball starting out of sources downloaded
-# from kernel.org, but without distributing non-Free Software
-# yourself, because xdelta (unlike patches) is not reversible: the
-# removed bits are not present in it at all.
-
-# xdelta version 3 uses different command line syntax, and it switched
-# to the more standardized but less efficient vcdiff file format.
-# This script will also produce a vcdiff file if xdelta3 is present,
-# and it expects the xdelta program to use the version 1 syntax.
-
-# To enable you to check the differences between the tarballs, a patch
-# file is generated in linux-libre-$kver-gnu$extra.patch. This patch
-# file contains the non-Free blobs, even though in reversed form, so
-# its distribution is discouraged.
-
-# The tar files and binary deltas are finally compressed with bzip2,
-# and optionally with lzip and xz too, if the compressors are
-# available.
-
-# At the end, the script attempts to generate a digital signature for
-# the newly-created tarball. This is the last thing the script does,
-# so interrupting it at that point to skip the signing won't fail to
-# do anything else.
-
-# It is safe to interrupt the script at any other point. When it gets
-# a ^C (other than during signing), it starts cleaning up all of its
-# temporary and output files. If you insist, it may leave junk
-# behind, and then it will refuse to run again before you clean it up
-# by hand. It takes extra care to avoid overwriting useful files.
-
-# If deblob-$mver finds any unexpected situation, it will error out,
-# and then deblob-main will quit. Pass --force to deblob-main, before
-# any other argument, for deblob-main to ignore any such situations.
