# Makeself version 2.1.x
# by Stephane Peter <megastep@megastep.org>
#
# $Id: makeself.sh,v 1.66 2009-01-08 02:24:53 megastep Exp $
#
# Utility to create self-extracting tar.gz archives.
# The resulting archive is a file holding the tar.gz archive with
# a small Shell script stub that uncompresses the archive to a temporary
# directory and then executes a given script from withing that directory.
#
# Makeself home page: http://www.megastep.org/makeself/
#
# Version 2.0 is a rewrite of version 1.0 to make the code easier to read and maintain.
#
# Version history :
# - 1.0 : Initial public release
# - 1.1 : The archive can be passed parameters that will be passed on to
# the embedded script, thanks to John C. Quillan
# - 1.2 : Package distribution, bzip2 compression, more command line options,
# support for non-temporary archives. Ideas thanks to Francois Petitjean
# - 1.3 : More patches from Bjarni R. Einarsson and Francois Petitjean:
# Support for no compression (--nocomp), script is no longer mandatory,
# automatic launch in an xterm, optional verbose output, and -target
# archive option to indicate where to extract the files.
# - 1.4 : Improved UNIX compatibility (Francois Petitjean)
# Automatic integrity checking, support of LSM files (Francois Petitjean)
# - 1.5 : Many bugfixes. Optionally disable xterm spawning.
# - 1.5.1 : More bugfixes, added archive options -list and -check.
# - 1.5.2 : Cosmetic changes to inform the user of what's going on with big
# archives (Quake III demo)
# - 1.5.3 : Check for validity of the DISPLAY variable before launching an xterm.
# More verbosity in xterms and check for embedded command's return value.
# Bugfix for Debian 2.0 systems that have a different "print" command.
# - 1.5.4 : Many bugfixes. Print out a message if the extraction failed.
# - 1.5.5 : More bugfixes. Added support for SETUP_NOCHECK environment variable to
# bypass checksum verification of archives.
# - 1.6.0 : Compute MD5 checksums with the md5sum command (patch from Ryan Gordon)
# - 2.0 : Brand new rewrite, cleaner architecture, separated header and UNIX ports.
# - 2.0.1 : Added --copy
# - 2.1.0 : Allow multiple tarballs to be stored in one archive, and incremental updates.
# Added --nochown for archives
# Stopped doing redundant checksums when not necesary
# - 2.1.1 : Work around insane behavior from certain Linux distros with no 'uncompress' command
# Cleaned up the code to handle error codes from compress. Simplified the extraction code.
# - 2.1.2 : Some bug fixes. Use head -n to avoid problems.
# - 2.1.3 : Bug fixes with command line when spawning terminals.
# Added --tar for archives, allowing to give arbitrary arguments to tar on the contents of the archive.
# Added --noexec to prevent execution of embedded scripts.
# Added --nomd5 and --nocrc to avoid creating checksums in archives.
# Added command used to create the archive in --info output.
# Run the embedded script through eval.
# - 2.1.4 : Fixed --info output.
# Generate random directory name when extracting files to . to avoid problems. (Jason Trent)
# Better handling of errors with wrong permissions for the directory containing the files. (Jason Trent)
# Avoid some race conditions (Ludwig Nussel)
# Unset the $CDPATH variable to avoid problems if it is set. (Debian)
# Better handling of dot files in the archive directory.
# - 2.1.5 : Made the md5sum detection consistent with the header code.
# Check for the presence of the archive directory
# Added --encrypt for symmetric encryption through gpg (Eric Windisch)
# Added support for the digest command on Solaris 10 for MD5 checksums
# Check for available disk space before extracting to the target directory (Andreas Schweitzer)
# Allow extraction to run asynchronously (patch by Peter Hatch)
# Use file descriptors internally to avoid error messages (patch by Kay Tiong Khoo)
# - 2.1.6 : Replaced one dot per file progress with a realtime progress percentage and a spining cursor (Guy Baconniere)
# Added --noprogress to prevent showing the progress during the decompression (Guy Baconniere)
# Added --target dir to allow extracting directly to a target directory (Guy Baconniere)
