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).

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

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