#
# purpose:	Set the proper colormode and start web.
#
# details:	Uses the SPRGB_DIR environment variable (which is required by
# 		Web) to get the correct path. SPRGB_DIR is supposed to end in a
# 		trailing slash (/) but this is commonly forgotten, so we deal
# 		with that situation.
#
#		For simplicity's sake I may change the script to merely assume
#		that the Web_resources_linux24 file is in the same directory
#		as this script. This seems reasonable since the web/bin
#		directory is supposed to be in the user's executable path if
#		SPIDER/Web is properly configured.
#
# history: 	060203 - updated to reflect SPIDER 13.00's preference of
#		putting Web binaries in web/bin instead of web/src.
#
#		040901 - updated to reflect name change of Web executable to
#		web_linux_24.
#
#		030115 - updated to change the root window's VisualClass back
#		to the previous setting (xrdb -remove) after exiting Web.
#
