commit 9c4f27de6191ff54992cdf0746015c94aaa90678
Author: Alexey Tourbin <at на altlinux>

    moved functions and find-package from rpm-build to rpm, added .provides.sh
    
    This will allow to relax rpm-build-* dependencies, hopefully without adding
    new essential dependencies to rpm (note that rpm already depends on sh and
    coreutils; now this also includes grep, and possibly should include sed,
    awk, and gzip).
    
    Consider mono-mcs package, which is mono C# compiler.  Recently I added
    dependency on rpm-build-mono to this package, to enable automatic support
    for mono dependencies whenever mono compiler is used.  Now the problem
    is that rpm-build-mono depends on rpm-build (via /usr/lib/rpm/functions),
    and rpm-build in turn requires a lot of packages, e.g. gcc and autotools,
    for the purpose of populating base build environment.
    
    To put it another way, the problem is that it is impossible to install
    mono compiler (with automatic support for mono dependencies) without also
    installing gcc and stuff, which is roughly 100M of unrelated packages.
    
    This seems like a minor problem to me, since every "devel" package (including
    compilers) can conventionally require base build environment.  However,
    Alexander Bokovoy argues that school kids desperately need mono-mcs compiler
    on their desktops without gcc and another stuff from the base build environment!
    
    The upshot is that possibly we want to relax rpm-build-* dependencies,
    so that those "support for dependencies" packages do not require
    full-fledged rpm-build.  The easiest way to accomplish this is to
    move /usr/lib/rpm/functions from rpm-build to rpm package.  I also
    choose to move /usr/lib/rpm/find-package as well, along with making
    /usr/lib/rpm/.provides.sh, so that rpm-build-* packages depend on
    something like /usr/lib/rpm(Fatal), not just rpm.
