                makeself - Make self-extractable archives on Unix
 
-   [1]makeself.sh is a small shell script that generates a
-   self-extractable tar.gz archive from a directory. The resulting file
-   appears as a shell script (many of those have a .run suffix), and can
-   be launched as is. The archive will then uncompress itself to a
-   temporary directory and an optional arbitrary command will be executed
-   (for example an installation script). This is pretty similar to
-   archives generated with WinZip Self-Extractor in the Windows world.
-   Makeself archives also include checksums for integrity self-validation
-   (CRC and/or MD5 checksums).
-
-   The makeself.sh script itself is used only to create the archives from
-   a directory of files. The resultant archive is actually a compressed
-   (using gzip, bzip2, or compress) TAR archive, with a small shell
-   script stub at the beginning. This small stub performs all the steps
-   of extracting the files, running the embedded command, and removing
-   the temporary files when it's all over. All what the user has to do to
-   install the software contained in such an archive is to "run" the
-   archive, i.e sh nice-software.run. I recommend using the "run" (which
-   was introduced by some Makeself archives released by Loki Software) or

 Usage
 
    The syntax of makeself is the following:
 
-   makeself.sh [args] archive_dir file_name label startup_script
-   [script_args]
+   makeself.sh [args] archive_dir file_name label startup_script [script_args]
      * args are optional options for Makeself. The available ones are :
-          + --version : Prints the version number on stdout, then exits
+          + --version  :  Prints the version number on stdout, then exits
             immediately
-          + --gzip : Use gzip for compression (is the default on
-            platforms on which gzip is commonly available, like Linux)
-          + --bzip2 : Use bzip2 instead of gzip for better compression.
-            The bzip2 command must be available in the command path. I
-            recommend that you set the prefix to something like
-            '.bz2.run' for the archive, so that potential users know that
-            they'll need bzip2 to extract it.
-          + --compress : Use the UNIX "compress" command to compress the
-            data. This should be the default on all platforms that don't
-            have gzip available.
-          + --nocomp : Do not use any compression for the archive, which
-            will then be an uncompressed TAR.
-          + --notemp : The generated archive will not extract the files
-            to a temporary directory, but in a new directory created in
-            the current directory. This is better to distribute software
-            packages that may extract and compile by themselves (i.e.
-            launch the compilation through the embedded script).
+          + --gzip : Use gzip for compression (is the default on platforms on
+            which gzip is commonly available, like Linux)

-            instead of in a subdirectory. This option implies --notemp
-            above.
-          + --follow : Follow the symbolic links inside of the archive
-            directory, i.e. store the files that are being pointed to
-            instead of the links themselves.
-          + --append (new in 2.1.x): Append data to an existing archive,
-            instead of creating a new one. In this mode, the settings
-            from the original archive are reused (compression type,
-            label, embedded script), and thus don't need to be specified
-            again on the command line.
-          + --header : Makeself 2.0 uses a separate file to store the
-            header stub, called "makeself-header.sh". By default, it is
-            assumed that it is stored in the same location as
-            makeself.sh. This option can be used to specify its actual
-            location if it is stored someplace else.
-          + --copy : Upon extraction, the archive will first extract
-            itself to a temporary directory. The main application of this
-            is to allow self-contained installers stored in a Makeself
-            archive on a CD, when the installer program will later need
-            to unmount the CD and allow a new one to be inserted. This
-            prevents "Filesystem busy" errors for installers that span
-            multiple CDs.
-          + --nox11 : Disable the automatic spawning of a new terminal in
-            X11.
-          + --nowait : When executed from a new X11 terminal, disable the
-            user prompt at the end of the script execution.
-          + --nomd5 and --nocrc : Disable the creation of a MD5 / CRC
-            checksum for the archive. This speeds up the extraction
-            process if integrity checking is not necessary.
-          + --lsm file : Provide and LSM file to makeself, that will be
+            instead of in a subdirectory. This option implies --notemp above.
+          + --follow  :  Follow  the symbolic links inside of the archive
+            directory, i.e. store the files that are being pointed to instead
+            of the links themselves.
+          + --append  (new in 2.1.x): Append data to an existing archive,
+            instead of creating a new one. In this mode, the settings from the
+            original archive are reused (compression type, label, embedded
+            script), and thus don't need to be specified again on the command
+            line.

+            errors for installers that span multiple CDs.

+          + --nowait : When executed from a new X11 terminal, disable the user
+            prompt at the end of the script execution.
+          + --nomd5 and --nocrc : Disable the creation of a MD5 / CRC checksum
+            for the archive. This speeds up the extraction process if integrity
+            checking is not necessary.
+          + --lsm  file  : Provide and LSM file to makeself, that will be
             embedded in the generated archive. LSM files are describing a
-            software package in a way that is easily parseable. The LSM
-            entry can then be later retrieved using the '-lsm' argument
-            to the archive. An exemple of a LSM file is provided with

-   Archives generated with Makeself 2.1 can be passed the following
-   arguments:
-
-     * --keep : Prevent the files to be extracted in a temporary
-       directory that will be removed after the embedded script's
-       execution. The files will then be extracted in the current working
-       directory and will stay here until you remove them.

-     * --nochown : By default, a "chown -R" command is run on the target
-       directory after extraction, so that all files belong to the
-       current user. This is mostly needed if you are running as root, as
-       tar will then try to recreate the initial user ownerships. You may

 Version history
 
      * v1.0: Initial public release
-     * v1.1: The archive can be passed parameters that will be passed on
-       to the embedded script, thanks to John C. Quillan
-     * v1.2: Cosmetic updates, support for bzip2 compression and
-       non-temporary archives. Many ideas thanks to Francois Petitjean.
-     * v1.3: 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.
-     * v1.4: Many patches from Francois Petitjean: improved UNIX
-       compatibility, automatic integrity checking, support of LSM files
-       to get info on the package at run time..
-     * v1.5.x: A lot of bugfixes, and many other patches, including
-       automatic verification through the usage of checksums. Version
-       1.5.5 was the stable release for a long time, even though the Web
-       page didn't get updated ;-). Makeself was also officially made a
-       part of the [11]Loki Setup installer, and its source is being
-       maintained as part of this package.
-     * v2.0: Complete internal rewrite of Makeself. The command-line
-       parsing was vastly improved, the overall maintenance of the
-       package was greatly improved by separating the stub from
-       makeself.sh. Also Makeself was ported and tested to a variety of
-       Unix platforms.
-     * v2.0.1: First public release of the new 2.0 branch. Prior versions
-       are officially obsoleted. This release introduced the '--copy'
-       argument that was introduced in response to a need for the
-       [12]UT2K3 Linux installer.
-     * v2.1.0: Big change : Makeself can now support multiple embedded
-       tarballs, each stored separately with their own checksums. An
-       existing archive can be updated with the --append flag. Checksums
-       are also better managed, and the --nochown option for archives
-       appeared.
-     * v2.1.1: Fixes related to the Unix compression (compress command).
-       Some Linux distributions made the insane choice to make it
-       unavailable, even though gzip is capable of uncompressing these
-       files, plus some more bugfixes in the extraction and checksum
-       code.
-     * v2.1.2: Some bug fixes. Use head -n to avoid problems with POSIX
+     * v1.1: The archive can be passed parameters that will be passed on to the
+       embedded script, thanks to John C. Quillan

+     * v2.1.0:  Big  change  : Makeself can now support multiple embedded
+       tarballs, each stored separately with their own checksums. An existing
+       archive can be updated with the --append flag. Checksums are also better
+       managed, and the --nochown option for archives appeared.
+     * v2.1.1: Fixes related to the Unix compression (compress command). Some
+       Linux distributions made the insane choice to make it unavailable, even
+       though gzip is capable of uncompressing these files, plus some more
+       bugfixes in the extraction and checksum code.
+     * v2.1.2:  Some  bug fixes. Use head -n to avoid problems with POSIX
        conformance.
-     * v2.1.3: Bug fixes with the command line when spawning terminals.
-       Added --tar, --noexec for archives. Added --nomd5 and --nomd5 to
-       avoid creating checksums in archives. The embedded script is now
-       run through "eval". The --info output now includes the command
-       used to create the archive. A man page was contributed by Bartosz
-       Fenski.
+     * v2.1.3: Bug fixes with the command line when spawning terminals. Added
+       --tar,  --noexec  for archives. Added --nomd5 and --nocrc to avoid
+       creating checksums in archives. The embedded script is now run through
+       "eval". The --info output now includes the command used to create the
+       archive. A man page was contributed by Bartosz Fenski.
+     * v2.1.4:  Fixed  --info output. Generate random directory name when
+       extracting files to . to avoid problems. Better handling of errors with
+       wrong permissions for the directory containing the files. Avoid some
+       race conditions, Unset the $CDPATH variable to avoid problems if it is
+       set. Better handling of dot files in the archive directory.
