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

DESCRIPTION:
	This script simplifies 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.
	It is helpful when bootstrapping a demo server with a sample data
	set, complete with broker, Perl/P4Perl, and Python/P4Python.

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 (unless running
	with '-fast').

	The 'wget' utility must be installed and available in the
	PATH (unless running with '-local').  Mac OSX users:  'wget'
	is not installed with Mac OSX by default, at least not as of
	OSX 10.11/El Capitan.  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).

	The '-B' and '-local' arguments are mutually exclusive.

 -local
	By default, various files and executables are downloaded from
	the Perforce Workshop or the Perforce FTP server as needed.
	With '-local', any missing files are treated as an error
	condition.

	The '-B' and '-local' arguments are mutually exclusive.

 -fast	Specify '-fast' to skip installation of Perl auxiliary things
	like Perl, Python, P4Perl, P4Python.

	The '-fast' argument changes the check for GCC/G++
	from a fatal error to a warning message.

 -no_ssl
	By default, the Perforce server is setup SSL-enabled.  Specify
	'-no_ssl' to avoid using SSL feature.

 -no_sd
	By default, the Perforce Sample Depot data set is loaded.
	Specify '-no_sd' to skip loading the Sample Depot.

 -p <dir1>[,<dir2>,...]>]
	Specify a comma-delimited list of directories under /p4/common
	to preserve that would otherwise be removed.  Directories must
	be specified as paths relative to /p4/common, and cannot contain
	spaces.

	For example, the value '-p config,bin/triggers' would preserve the
	/p4/common/config and /p4/common/bin/triggers directories.

	Directories specified are moved aside to a temporary working area
	before the SDP folders are removed.  After installation, they are
	moved back via an 'rsync' command with no '--delete' option.  This
	means any files that overlap with the stock install are replaced
	by ones that originally existed, but non-overlapping files are not
	removed.

	This is intended to be useful for developing test suites that
	install server under /p4/common/bin, e.g. Component Based Development
	scripts which install under /p4/common/bin/cbd would use '-p bin/cbd'
 
 -b <branch>
	The default SDP install method is to clone the SDP from the main
	branch in The Workshop ($WorkshopPort).  Specify '-b' to use
	a different branch, e.g. 'dev'.

 -t <tarfile>
	Specify a tarfile to use, e.g. '-t sdp.Unix.2016.1.20028.tgz', or
	use the special value '-t default' to use the default SDP tarfile,
	$SDPTar

	The specified tar file must exist here:
	https://swarm.workshop.perforce.com/projects/perforce-software-sdp/files/downloads

	If '-t <tarfile>' is not specified, default install method is
	used instead, which is to clone the SDP main branch from The
	Workshop ($WorkshopPort).

	Use '-t' to get a known version of the SDP for testing.  Avoid '-t'
	to test with the very latest SDP from a given branch (see '-b' above
	for more info), even if the latest has not yet been packaged into a
	distribution tar file.

 -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 /tmp/log.reset_sdp
