rpmconf-matt: Tool for three-way merge of RPM configuration files

[Matt McCutchen]

Hi Fedora users (FYI to rpmconf maintainer),

Several years ago, I wrote a little tool to help automate a three-way
merge of RPM-managed configuration files after package upgrades.  This
has been a sore omission from Fedora for years:

https://lists.fedoraproject.org/archives/list/[e-mail]/...

And I've finally decided to make the tool public on my web site:

https://mattmccutchen.net/utils/utils.git/blob/HEAD:/rpmconf-matt

It's currently crude in a lot of ways, but others who are still letting
RPM mutate their root filesystem (rather than using something like
Silverblue) may already find it useful with minimal modifications.  If
enough people are interested, I may be motivated to clean it up and try
to get the functionality added to the rpmconf in Fedora.  If people
want to help, that's even better.

Let me know if there's another place I should promote this.  Also
please let me know if I've overlooked an existing tool that does the
same thing; a quick web search today didn't find any.

Cheers,
Matt
