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 com-
       pared.

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 specify
	      "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  comparison  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://mir-
	      rors.fedoraproject.org/metalink?repo=fedora-source-16&arch=i386' --size --simple --downgrade
