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 necessary -# - 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 spinning 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) -# - 2.2.0 : Many bugfixes, updates and contributions from users. Check out the project page on Github for the details. -# - 2.3.0 : Option to specify packaging date to enable byte-for-byte reproducibility.
