# Build
# By Bryan Atsatt
#
# Syntax:	Build [options] name [name [name]]
#
# Description:	This script will Make the specified makefile from the {MakeFiles} directory
# 		and execute its output.  It expects the filenames in the {MakeFiles} directory
#		to be in the format "make.name" where "name" is the name passed to Build.
#
# Options:	-l	Generate a listing in {Listings} directory. Forces -e option.
#		-o	Open makeout file so you can see what Make outputs.
#		-e	Force Make to rebuild everything.
#		-p	Write progress information to standard output.
#		-s	Suppress update dialog.	
#
# All of the Make options which do not have two parts (i.e. "-f makefile") can also
# be passed as options.
#
# The following names can be used in place of "os";  these are especially useful when creating
# listings because they will only list the named module:
#
#	scm, bank0, devmgr, devdisp, cache, init, gquit, loader
#
# If you type "all" for the name, all of the makefiles in the {MakeFiles} directory will be
# processed.   
#

#
# Check for zero parameters case...
#
if !{#}
	echo "### Build - Filename required." >> dev:StdOut
	exit 0
end

#
# Parse parameters as long as this is not a recursive call...
