+Title:		sc Spreadsheet Calculator
+Version:	7.16
+Entered-date:	2002-9-19
+Description:	sc is a free curses-based spreadsheet program that uses
+		key bindings similar to vi and less.
+Keywords:	spreadsheet calculator console textmode curses ncurses
+Author:		Too numerous to mention.
+Maintained-by:	nrocinu@myrealbox.com (Chuck Martin)
+Primary-site:	ibiblio.org /pub/Linux/apps/financial/spreadsheet
+Alternate-site:
+Original-site:
+Platforms:	Pre-7.x versions presumably worked on any Unix or Unix
+		clone, as well as VMS and DOS.  Hopefully, this is still
+		true, but it's only been tested on Linux.
+Copying-policy:	Public domain

+# HOW TO EDIT THIS FILE:
+# The "handy ruler" below makes it easier to edit a package description. Line
+# up the first '|' above the ':' following the base package name, and the '|'
+# on the right side marks the last column you can put a character in. You must
+# make exactly 11 lines for the formatting to be correct. It's also
+# customary to leave one space after the ':'.
