+=== CONSTANTS ===
+
+*POOL_FLAG_PROMOTEEPOCH*::
+  Promote the epoch of the providing dependency to the requesting
+  dependency if it does not contain an epoch. Used at some time
+  in old rpm versions, modern systems should never need this.
+
+*POOL_FLAG_FORBIDSELFCONFLICTS*::
+  Disallow the installation of packages that conflict with themselfs.
+  Debian always allowd self-conflicting packages, rpm used to forbid
+  them but switched to also allowing them recently.

+  Make obsolete type dependency match against provides instead of
+  just the name and version of packages. Very old versions of rpm
+  used the name/version, then it got switched to provides and later
+  switched back again to just name/version.
+
+*POOL_FLAG_IMPLICITOBSOLETEUSESPROVIDES*::
+  An implicit obsoletes is the internal mechanism to remove the
+  old package on an update. The default is to remove all packages
+  with the same name, rpm-5 switched to also removing packages
+  providing the same name.
+
+*POOL_FLAG_OBSOLETEUSESCOLORS*::
+  Rpm's multilib implementation (used in RedHat and Fedora)
+  distinguishes between 32bit and 64bit packages (the terminology
+  is that they have a different color). If obsolteusescolors is
+  set, packages with different colors will not obsolete each other.

+  when checking for dependency, thus you may not install a package
+  that is obsoleted by some other installed package, unless you

+  package. This was changed to ignoring just the implicit obsoletes,
+  thus you may install multiple versions of the same name, but
