Hi Jeff,

The person with many makepkg changes on their branch would be me, but 
the vast majority have now been applied to the master git branch.

Note that with the changes that are now in the pacmans git repo, there 
is support for build() and package() functions in PKGBUILDs.  When the 
package() function is present, it is run under fakeroot but the build() 
function is not.  Otherwise it is backwards compatible.

I like the idea of an additional check() function. However, I could 
implement it slightly differently - instead of a makepkg.conf flag to 
run the check() function or not, I think it may be better to add a 
--check flag to makepkg so people specify when to run it.

Anyway, I think the key point here is that if you have ideas for 
pacman/makepkg features and want to implement them, it is probably best 
to email here first to see what is already going on.
