This is Debian GNU's prepackaged version of the FSF's GNU ed utility. The classic unix line editor, ed is a line-oriented text editor. It is used to create, display, modify and otherwise manipulate text files. This package was put together by me, James Troup , from the GNU sources, which I obtained from: ftp://ftp.gnu.org/pub/gnu/ed/ed-0.7.tar.bz2 The changes were small: o adding support for the Debian package maintenance scheme, by adding various debian/* files. o buf.c (open_sbuf): use tmpfile() and not mktemp(). o glbl.c (exec_global), io.c (read_stream, get_stream_line), main.c (main, exec_command, get_matching_node_addr, strip_escapes), re.c (get_compiled_pattern), sub.c (extract_subst_template, substitute_matching_text): parentheses to quiet -Wall. o ed.1: various fixes by Matt Kraai Program Copyright (C) 1993, 1994 Andrew Moore, Talke Studio.
