fix: stop using "magic" numbers in string operations for the copyannofile2log feature fix: When using the copylogfromannofile workaround, extract the build ID and build duration and add to the log as these are useful for analysis. The log should now be identical to the stdout file. fix: Remove extra blank lines from output in copylogfromannofile mode.

# Makeself version 2.1.x
#  by Stephane Peter <megastep@megastep.org>

#
# 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)
