+YUM AUTHORS
+----------------
+
+Yum is currently maintained by Seth Vidal <skvidal@phy.duke.edu>. Yum was
+written to scratch an itch for some folks at duke, specifically seth. It was
+based in huge parts off of code from yup - the yellowdog updater. Yum has used 
+a bunch of code from other gpl'd projects - up2date, anaconda and yup.  Folks below
+are thanked for their help/code/smarts.

+For usage information, please see the README.
+
+yum uses a relatively standard ./configure ; make ; make install to
+work, although it is recommended that you install an RPM as yum
+requires that it be installed as an RPM.  
+
+If checking code out of CVS, you will need to run autoconf first to
+create the configure script.

+Yum - an automatic updater and installer for rpm-based systems
+-------------------------------------
+
+Included programs:
+/usr/sbin/yum		Main program
+/usr/sbin/yum-arch	Generate the database that yum downloads
+
+Basic usage description follows:
+
+Yum is run with one of the following options:
+
+ - update [package list]
+	If run without any packages, Yum will automatically upgrade every
+	currently installed package.  If one or more packages are
+	specified, Yum will only update the packages listed.
+
+ - install <package list>
+	Yum will install the latest version of the specified package
+	(don't specify version information).
+
+ - remove <package list>
+	Yum will remove the specified packages from the system.
+
+ - yum list [package list]
+        List available packages
+
+yum-arch is run from the distribution site in order to create the
+databases which Yum determines remote package availability.
+
+yum-arch is run in one of two ways:
+	yum-arch <top level of archive>
+
+
+
+

+Things that must be done:
+
+Put the sigcheck function in :)
+ make it an option per server not global.
+
+fix the nevral so newest wins for the headerInfoNevral by default and
+last-in as an option.
+
+Implement the comps parsing and group* functions
+Implement clean * - shouldn't be terribly hard.
+
+Implement pkg excludes for new packages on the client side
+Implement pkg excludes on the server side
+Implement a server-side config file or commandline option to let it know where to get the comps/group list from
+
+Make it possible to have an http-accesible global conf file for excludes and
+what not.
+
+gzip the headers so they are smaller to move across the network
+
+Implement a status/progress bar for downloading pkgs
+Make -q and -d 0 VERY quiet
+Make the syslog, log be sane
+
+rewrite the man pages so they have some meaning :)
+
+Work on making the frontend more spiffy
+
+quiet down the callback for rpm installs if -q is invoked.
+
+work on making ftp and file urls work
+
+test on non x86 archs and make sure grub and lilo stuff are not run for this arch
+possibly implement a per-arch pkgaction.kernelupdate function
