DESCRIPTION:
	This script SHOULD NEVER EXIST on a Production Perforce server.

	It is designed simplify the process of testing an SDP installation,
	repetitively blasting all process by the 'perforce' user and resetting
	the SDP from the ground up, blasting typical SDP folders each time.
	This could be helpful bootstrapping a demo server with a sample data set.

PLATFORM SUPPORT:
	This works on Red Hat Linux, CentOS, and Mac OSX (Mavericks or
	Yosemitie) platforms.  It works on CentOS 6.4 and 6.5 and
	likely on other Linux derivatives with little or no modification.

	It currently supports only the bin.linux26x86_64 (Linux) and
	bin.darwin90x86_64 (Mac OSX/Darwin) architectures.

REQUIREMENTS:
	Development utilities such as 'make' and the 'gcc' compiler
	must be installed and available in the PATH.

	The 'wget' utility must be installed and available in the
	PATH.  Mac OSX users:  'wget' is not installed with Mac OSX
	by default, at least not os of OSX 10.10/Yosemite.  It can be
	acquired and compiled.  For example, see:
	http://osxdaily.com/2012/05/22/install-wget-mac-os-x/

OPTIONS:
 -B	Specify '-B' to blast base SDP dirs, for a clean start.
	Otherwise, downloaded components from earlier runs will
	be used (which should be fine if they were run recently).
 
 -D     Set extreme debugging verbosity.

HELP OPTIONS:
 -h	Display short help message
 -man	Display man-style help message

EXAMPLES:
	Typical usage:
	sudo bash # Because you need to run as root.
	cd /where/this/script/is
	./reset_sdp.sh -B 2>&1 | tee log.reset_sdp

# Change User Description Committed
#23 15829 C. Thomas Tyler Moved Helix Installer to new Workshop Standard
for personal projects.
#22 15629 C. Thomas Tyler reset_sdp.sh v2.5.0:
* Updated SDP to 2015.1.15607.
* Added '-C' (clean) flag to blast /depotdata/p4/common.
#21 15611 C. Thomas Tyler reset_sdp.sh v2.4.9:
* Updated default Swarm to 2015.2.
* Fixed mostly harmless bug attempting to pull a non-existing file from the web.
#20 15060 C. Thomas Tyler Rollback of Copy Up done with a new utility that apparently needs some work.
#19 15051 C. Thomas Tyler Copy Up using 'p4 copy -r -b tom_tyler-hi-dev'
#18 15007 C. Thomas Tyler Fixed expression.
#17 14987 C. Thomas Tyler Reduced excessive noise from from rsync and tar commands.

Added '--delete' to rsync commands handling the Sample Depot
to force a clean reset.

Added clear completion messages.
#16 14973 C. Thomas Tyler Added -no_ssl flag.
#15 14956 C. Thomas Tyler Fixed 'ps' check.
#14 14954 C. Thomas Tyler Fixed typo in case sensitivity mod.
#13 14953 C. Thomas Tyler Updated various settings to match changes in SDP.
Removed generation of a duplicate broker config file.
#12 14952 C. Thomas Tyler Adjusted case sensitivitiy to be case-sensitive on Linux,
the opposite of the SDP default.
#11 14949 C. Thomas Tyler Enhanced to ensure that 'reset_sdp.sh' is the only script
required.  It now downloads all other scripts and data files as
needed.
#10 14910 C. Thomas Tyler Added initialtion of empty /depotdata /metadata and /logs
dirs.
#9 14903 C. Thomas Tyler Fixed issue running under Vagrant.
#8 14902 C. Thomas Tyler Changed default list of SDP instances to initialize from
"1 12 abc" (illustrating ability to use named rather than
number instances) to just "1", which is mostly all that's
wanted for testing and pilot installations.
#7 14901 C. Thomas Tyler Fixed a typo in 'chmod' call.
#6 14188 C. Thomas Tyler Updated SDP version.
#5 14120 C. Thomas Tyler Moved sample depot checkpoint load to configurator script.
Added '-fast' flag to speed up testing.
Various minor tweaks.
#4 14106 C. Thomas Tyler Implemented Sample Depot SDP configurator script.

Tightened logic around process kill statement, and made it
work for Linux/Mac.
#3 14063 C. Thomas Tyler Added generation of initial live checkpoint for each instance.
Adjusted permissions on downloads folder.
Removed bad code fragements.
Cosmetic enhancement to the password.
#2 14033 C. Thomas Tyler Added script to transform stock Sample Depot data set to be
SDP compliant (mostly a stub at this point).  Various improvements
to reset_sdp.sh and the wrapper r.sh.
#1 13940 C. Thomas Tyler Added my personal reset_sdp test script.
 DO NOT DEPLOY on a live server.
