# =============================	Usage =============================

# <<<< This section is deleted in the "binary" distribution.

# make all
#	Compile the entire program.  This is the default target.

# >>>> End of deleted section.

# make check
#	Perform self-tests.  The program must be compiled first, but need
#	not be installed.

# make install
#	Compile the program and copy the executables, libraries, and so
#	on to the directories in which they should reside for actual use.
#	These directories, specified below, will be created if they don't
#	already exist.

# make uninstall
#	Delete the files that the "install" target would create.

# <<<< This section is deleted in the "binary" distribution.

# make clean
#	Delete all files from the current directory that are normally
#	created by building the program.

# make distclean
#	Delete all files from the current directory that are created by
#	configuring or building the program.  If you have unpacked the
#	source and built the program without creating any other files,
#	`make distclean' should leave only the files that were in the
#	distribution.

# make maintainer-clean
#	Delete everything from the current directory that can be
#	reconstructed with this Makefile.

# Directory and name of the startup file.  This is compiled into the
