NAME
	alterheader - to alter header information in an MRC file

SYNOPSIS
	alterheader

DESCRIPTION
	Alterheader allows one to alter header information in an MRC file 
	without rewriting the file.  For each header entry selected by the
	user, the program prints the current values and asks for new values,
	checking for legality in some cases.  Entering HELP will get a brief
	description of the options.  However, the user is expected to know
	what the header entries mean; consult the MRC documentation.

        The file name can be entered on the command line; if not, the program
        will ask for it.
