| 8 | # Utility to create self-extracting tar.gz archives.
|
|---|
| 9 | # The resulting archive is a file holding the tar.gz archive with
|
|---|
| 10 | # a small Shell script stub that uncompresses the archive to a temporary
|
|---|
| 11 | # directory and then executes a given script from withing that directory.

| 15 | # Version 2.0 is a rewrite of version 1.0 to make the code easier to read and maintain.
|
|---|
| 16 | #
|
|---|
| 17 | # Version history :
|
|---|
| 18 | # - 1.0 : Initial public release
|
|---|
| 19 | # - 1.1 : The archive can be passed parameters that will be passed on to
|
|---|
| 20 | # the embedded script, thanks to John C. Quillan
|
|---|
| 21 | # - 1.2 : Package distribution, bzip2 compression, more command line options,
|
|---|
| 22 | # support for non-temporary archives. Ideas thanks to Francois Petitjean
|
|---|
| 23 | # - 1.3 : More patches from Bjarni R. Einarsson and Francois Petitjean:
|
|---|
| 24 | # Support for no compression (--nocomp), script is no longer mandatory,
|
|---|
| 25 | # automatic launch in an xterm, optional verbose output, and -target
|
|---|
| 26 | # archive option to indicate where to extract the files.
|
|---|
| 27 | # - 1.4 : Improved UNIX compatibility (Francois Petitjean)
|
|---|
| 28 | # Automatic integrity checking, support of LSM files (Francois Petitjean)
|
|---|
| 29 | # - 1.5 : Many bugfixes. Optionally disable xterm spawning.
|
|---|
| 30 | # - 1.5.1 : More bugfixes, added archive options -list and -check.
|
|---|
| 31 | # - 1.5.2 : Cosmetic changes to inform the user of what's going on with big
|
|---|
| 32 | # archives (Quake III demo)
|
|---|
| 33 | # - 1.5.3 : Check for validity of the DISPLAY variable before launching an xterm.
|
|---|
| 34 | # More verbosity in xterms and check for embedded command's return value.
|
|---|
| 35 | # Bugfix for Debian 2.0 systems that have a different "print" command.
|
|---|
| 36 | # - 1.5.4 : Many bugfixes. Print out a message if the extraction failed.
|
|---|
| 37 | # - 1.5.5 : More bugfixes. Added support for SETUP_NOCHECK environment variable to
|
|---|
| 38 | # bypass checksum verification of archives.
|
|---|
| 39 | # - 1.6.0 : Compute MD5 checksums with the md5sum command (patch from Ryan Gordon)
|
|---|
| 40 | # - 2.0 : Brand new rewrite, cleaner architecture, separated header and UNIX ports.
|
|---|
| 41 | # - 2.0.1 : Added --copy
|
|---|
| 42 | # - 2.1.0 : Allow multiple tarballs to be stored in one archive, and incremental updates.
|
|---|
| 43 | # Added --nochown for archives
|
|---|
| 44 | # Stopped doing redundant checksums when not necesary
|
|---|
| 45 | # - 2.1.1 : Work around insane behavior from certain Linux distros with no 'uncompress' command
|
|---|
| 46 | # Cleaned up the code to handle error codes from compress. Simplified the extraction code.
|
|---|
| 47 | # - 2.1.2 : Some bug fixes. Use head -n to avoid problems.
|
|---|
| 48 | # - 2.1.3 : Bug fixes with command line when spawning terminals.
|
|---|
| 49 | # Added --tar for archives, allowing to give arbitrary arguments to tar on the contents of the archive.
|
|---|
| 50 | # Added --noexec to prevent execution of embedded scripts.
|
|---|
| 51 | # Added --nomd5 and --nocrc to avoid creating checksums in archives.
|
|---|
| 52 | # Added command used to create the archive in --info output.
|
|---|
| 53 | # Run the embedded script through eval.
