Subject: Allow version comparison to contain epoch specifier

Adapting from RPM, follow the [epoch:]version[-release] syntax. We can also
borrow some of their parsing code for our purposes (thanks!).  Add some new
tests to our vercmp shell script tester for epoch comparisons, and then make
the code work with these newfangled epoch specifiers.

From bf46e04614b3740eea4a5e0d44767f57e1cffa4d Mon Sep 17 00:00:00 2001
From: Dan McGee <dan@archlinux.org>
Date: Mon, 10 Jan 2011 13:40:31 -0600
Subject: Remove epoch as an independent field

Instead, go the same route we have always taken with version-release in
libalpm and treat it all as one piece of information. Makepkg is the only
script that knows about epoch as a distinct value; from there on out we will
parse out the components as necessary.

This makes the code a lot simpler as far as epoch handling goes. The
downside here is that we are tossing some compatibility to the wind;
packages using force will have to be rebuilt with an incremented epoch to
keep their special status.

From b8ab96a270caa5d589c44c62d5664db156d94af7 Mon Sep 17 00:00:00 2001
From: Dan McGee <dan@archlinux.org>

Subject: makepkg: encode epoch in version specifier if > 0

This makes things consistent with everywhere else we are incorporating the
new optional epoch field. Add a helper function that forms the version
string for you and use it in makepkg where I found 'pkgver.*-.*pkgrel'.

This exposes a few shortcomings in a previous "Override pkgver" patch
(2020e629) in the install package and check if built functions.

Subject: doc: add a vercmp manpage

This includes info on version comparison that is very similar to the stuff
in the pacman manpage, but also a few vercmp examples, the return values,
and other fun stuff.

Also update the version comparison stuff in the pacman manpage.

+'vercmp' is used to determine the relationship between two given version

+*  > 0 : if ver1 > ver2

+
+Additionally, version strings can have an 'epoch' value defined that will
+overrule any version comparison (unless the epoch values are equal). This is

Allan, I had no idea you were not listed here. I think you count as an
