Lbzip2 0.13 (Default branch)

ImageLbzip2 is a Pthreads-based parallel bzip2/bunzip2 filter, passable to GNU tar with the --use-compress-program option. It isn't restricted to regular files on input, nor output. Successful splitting for decompression isn't guaranteed, just very likely (failure is detected). Splitting in both modes and compression itself occur with an approximate 900k block size. On an Athlon-64 X2 6000+, lbzip2 was 92% faster than standard bzip2 when compressing, and 45% faster when decompressing (based on wall clock time). Lbzip2 strives to be portable by requiring UNIX 98 APIs only, besides an unmodified libbz2.License: GNU General Public License (GPL)Changes:
Besides some code cleanup, various portability and other workarounds were introduced to cope with bugs in C libraries, shells, and upstream bzip2.Image

NAME
git-import-orig - Import an upstream source into a git repository SYNOPSIS
git-import-orig [ --verbose ] [ --upstream-version=version ] [ --[no-]merge ] [ --upstream-branch=branch_name ] [ --debian- branch=branch_name ] [ --upstream-vcs-tag=tag_name ] [ --[no-]sign-tags ] [ --keyid=gpg-keyid ] [ --upstream-tag=tag-format ] [ --fil- ter=pattern ] [ --[no-]pristine-tar ] [ --[no-]filter-pristine-tar ] [ --postimport=cmd ] [ --uscan ] upstream-source DESCRIPTION
git-import-orig imports upstream-source into the Git repository. upstream-source can either be a gzip or bzip2 compressed tar archive or an already unpacked source tree. If it is already of the form package-name_version.orig.tar.gz, the version information is read from the tar- ball's filename otherwise it can be given on the command line via --upstream-version. The sources are placed on the upstream branch (default: upstream), tagged and merged onto the debian branch (default: master). OPTIONS
--upstream-version=version -uversion The upstream version number --merge Merge the upstream branch to the debian branch after import --upstream-branch=branch_name The branch in the Git repository the upstream sources are put onto. Default is upstream. --debian-branch=branch_name The branch in the Git repository the Debian package is being developed on, default is master. After importing the new sources on the upstream branch, git-import-orig will try to merge the new version onto this branch. --upstream-vcs-tag=tag_name Add tag_name as additional parent to the commit of the upstream tarball. Useful when upstream uses git and you want to link to it's revision history. --verbose -v verbose execution --[no-]sign-tags GPG sign all created tags --keyid=gpg-keyid use this keyid for gpg signing tags --upstream-tag=tag-format use this tag format when tagging upstream versions, default is upstream/%(versions)s --import-msg=msg-format use this format string for the commit message when importing upstream versions, default is Imported Upstream version %(version)s --filter=pattern filter out files glob-matching pattern. Can be given multiple times. --pristine-tar generate pristine-tar delta file --filter-pristine-tar if using a filter also filter the files out of the tarball passed to pristine tar --postimport=cmd run cmd after the import. --uscan Use uscan to fetch new upstream version. CONFIGURATION FILES
Several gbp.conf files are parsed to set defaults for the above commandline arguments. See the [XRef to GBP.MAN.GBP.CONF] manpage for details. SEE ALSO
