## get_comp
## -----------
## get a component which will be wrapped into the install wrapper
## the component is fetched from the ftp server based on the locations
## and files identified by get_input_comp_files based on the WrappedProducts
## configuration script.
##
## Usage:
##	get_comp component bundle downloadsdir [comp.pl ...]
## Arguments:
##	component - one of OFED, SRP, VNIC, FF, FV or FM
##	bundle - one of Basic or IFS or TestTools or TESTS, PRs or RELEASE_NOTES
##	downloadsdir - intermediate local directory to put
##		component files will be downloaded into downloadsdir/component-bundle
##		downloadsdir will be created if needed
##  comp.pl - files to cat together to form comp.pl if product is NONE
## Required Environment (as set via setenv or similar tools):
##	TL_DIR
## 	BUILD_PLATFORM_OS_VENDOR_VERSION
##	BUILD_TARGET
##	BUILD_TARGET_OS_VENDOR
##
## Additional Environment:
##
##	FTPSERVER - ftp server to get files from of the form:
## 			ftp:password@server
##     defaults to: ftp:ftp@kop-sds-ftp
##  if FTPSERVER is cp:self@localhost the directory name for the source file
##	of the component is ignored.  In its place the directory name part of
##	FTPINT is used.  Note that typically FTPSERVER is derrived from FTPINT
##	hence an FTPINT of cp:self@localhost:mydir will do a cp from mydir
##  instead of an ftp.
##
##  SCPSERVER - host to get packages from via SCP. Takes the form:
##	"server" or "user@server:. Defaults to "phcvs2@phlsvlogin02"
##
##  SCPTOP - root directory to get SCP files from. Takes the form:
##  "directory". Defaults to "/nfs/site/proj/stlbuilds".
##
## This is designed for use in higher level scripts and makefiles, as such it
## will only download files which have not already been downloaded.
## It is expected that the higher level script or the makefile's clobber
## removes components-bundle directories in downloadsdir when it wants to
## force this to re-download
