NAME
       repodiff - list differences between two or more Yum repositories

SYNOPSIS
       repodiff --old=old_repo_baseurl --new=new_repo_baseurl

DESCRIPTION
       repodiff  is a program which will list differences between two sets of repositories.  Note
       that by default only source packages are compared.

GENERAL OPTIONS
       --old, -o
	      Add a repo. as an old repo. Note that if you prefix the url with "mirror:" then the
	      following url is treated as a mirror and not a baseurl.

       --new, -n
	      Add a repo. as an new repo. Note that if you prefix the url with "mirror:" then the
	      following url is treated as a mirror and not a baseurl.

       --archlist, -a
	      Add architectures to change the default from just comparing source packages.   Note
	      that  if	you want the same as a native "x86_64" architecture machine you just need
	      to pass "x86_64" (this is different from earlier versions where you needed to spec-
	      ify "x86_64,athlon,i686,i586,i486,i386,noarch" and you still got "src").

       --size, -s
	      Output additional data about the size of the changes.

       --compare-arch
	      Normally	packages  are just compared based on their name, this flag makes the com-
	      parison also use the arch. So foo.i386 and foo.x86_64 are different.

       --simple
	      Output a simple one line message for modified packages.

       --downgrade
	      Split the data for modified packages between upgraded and downgraded packages.

EXAMPLES
       Compare source pkgs in two local repos:
	      repodiff --old=/tmp/repo-old --new=/tmp/repo-new

       Compare x86_64 compat. binary pkgs in two remote repos, and two local one:
	      repodiff	 -a   x86_64	--old=http://example.com/repo1-old    --old=/tmp/repo-old
	      --new=http://example.com/repo1-new --new=/tmp/repo-new

       Compare x86_64 compat. binary pkgs, but also compare arch:
	      repodiff	   -a	  x86_64     --compare-arch    --old=http://example.com/repo1-old
	      --old=/tmp/repo-old --new=http://example.com/repo1-new --new=/tmp/repo-new

       Compare two releases of Fedora (15 => 16):
	      repodiff	    --old='mirror:https://mirrors.fedoraproject.org/metalink?repo=fedora-
	      source-15&arch=i386'	     --new='mirror:https://mirrors.fedoraproject.org/met-
	      alink?repo=fedora-source-16&arch=i386' --size --simple --downgrade
