[9fans] Installing the updates

["Doug Henderson" <djhender@telusplanet.net>]

In one of my porting project, <stdio.h> is included twice. This fails,
because, for instance, the way getchar is declared, first as an external
function, then as a macro. As a result, I added the usual protection code
(#ifndef <tag>; #define <tag>; <original body of header>; #endif) to
/sys/include/stdio.h, and others. I have also added some defines to allow
<event.h> and <mouse.h> to both be included without error/warning messages.
And I messed around with the ethernet driver code for my card (RealTeck
8029AS) trying to find out why it didn't work. Etc, etc.

I understand that wrap/inst will not overwrite my modified files, unless I
force it to do so. But I want to get a list of them, stash the source
changes to safety,
and overwrite all files with those from the release. Then, if still
necessary, I
will reapply the parts that actually fix a problem, instead of help diagnose
one. I want to have a clean updated system, with well known modifications.

Is there a wrap/inst expert out there that can provide some quick help.

How do I list the contents of a wrap archive?

How do I list the conflicts between a wrap archive and the current versions
(without actually installing anything)?

Thanks,
Doug
