#
#	Usage:
#		BuildCommands program [options…] > commands
#
#	The BuildCommands script writes the build commands for the specified
#	program (or target) to standard output.
#
#	Make is used to generate the build commands.  If file <program>.make
#	exists it is used as the makefile.	If not, file MakeFile is used.
#
#	The options specified are passed directly to Make, and control the
#	generation of the build commands.
