#  Description:   A script to summarize which, if any, files in the current   #
#                 CVS working directory ("sandbox") have actually changed.    #
#                                                                             #

#  Date:          Aug 27, 2002                                                #
#                                                                             #
#  Notes:         For most files, this is nothing more than a formatted       #
#                 wrapper around "cvs -n update".  However, in PRISM-land,    #
#                 Makefiles are dynamically modified during builds.  This     #
#                 means that they _ALWAYS_ show up as "modified" according    #
#                 to CVS, even though they aren't -- not in any significant   #
#                 way.  Therefore, this script pays special attention to      #
#                 PRISM Makefiles and tries to determine whether any of       #
#                 them have actually changed in a way that the developer      #
#                 would care about.                                           #
#                                                                             #
