From: lwall@devvax.UUCP
Newsgroups: comp.sources.bugs
Subject: patch 2.0 patch #11
Summary: This is an official patch for patch 2.0.  Please apply it.
Message-ID: <2169@devvax.JPL.NASA.GOV>
Date: 3 Jun 88 23:50:40 GMT
Organization: Jet Propulsion Laboratory
Lines: 1469
Posted: Fri Jun  3 19:50:40 1988

System: patch version 2.0
Patch #: 11
Priority: same as patch 10
Subject: patch 10 continued

Description:
	This is a new Configure.

Fix:	Unlike most patches, this one contains an entire new Configure
	script, which is shorter than the diffs.  Unshar this file in
	your patch source directory.  Please make sure you've just applied
	patch #10--this one doesn't check that patchlevel.h is correct.

	After applying:
		Configure	(or Configure -d)
		make
		make install

	If you are missing previous patches they can be obtained from me:

	Larry Wall
	lwall@jpl-devvax.jpl.nasa.gov

	If you send a mail message of the following form it will greatly speed
	processing:

	Subject: Command
	@SH mailpatch PATH patch 2.0 LIST
		   ^ note the c

	where PATH is a return path FROM ME TO YOU in Internet notation, and
	LIST is the number of one or more patches you need, separated by spaces,
	commas, and/or hyphens.  Saying 35- says everything from 35 to the end.

	You can also get the patches via anonymous FTP from
	jpl-devvax.jpl.nasa.gov (128.149.8.43).
