$0
	checks to make sure that your .cshrc, .login,
	.profile, .bashrc, and .kshenv are symbolic links to the
	comparable files in the $ETC directory.  All your shell
	customizations should be confined to your 'dot' files
	which are invoked from the 'dot' files.

	If you are missing any of the 'dot' files they will
	be copied from the $SKEL directory.

	If you substitute your own 'dot' files instead, it's likely that
	modules will not work for you, and you are unsupported if you
	experience any problems.

	This is version $VERSION .
