+Title:          netdata
+Version:        1.6.0
+Description:    netdata is a system for distributed real-time performance and health monitoring.
+                It provides unparalleled insights, in real-time, of everything happening on the
+                system it runs (including applications such as web and database servers), using
+                modern interactive web dashboards. netdata is fast and efficient, designed to
+                permanently run on all systems (physical & virtual servers, containers, IoT
+                devices), without disrupting their core function.

+# Makeself version 2.3.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://makeself.io/
+#
+# 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)
+# - 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. (Marc Pawlowsky)
