#    keys %SORTED_RECENT_FQN is the set of all package names

#    $SORTED_RECENT_FQN{$name} is an ordered list of the most recent

# for a short time there are these datastrutures but they are large

This is a web interface into the rpmdiff command.

The user is requested to enter two different packages to diff after
any one of the multiple submit buttons is pressed the difference will
be the next webpage loaded.  For convenience each package name is
listed once (in alphabetical order) and below it is checkbox of the
most recent $MAX_PICK_LIST versions of this package.  Any pick list
which is not actively picked by the user contains the string '(none)'.

The user should pick one package in the first column (this represents
the "old package") and one package in the second column (this
represents the "new package").  When the user wants to run the
difference any 'submit' button can be pressed.  The multiple submit
buttons are listed only for convenience to reduce hunting for a button
on the page.

Error reporting is very minimal and if an incorrect number of packages
is picked then the main page is displayed again.  It is suggested that
the user hit the default button if any problems are encountered using
the program.

Most users are only interested in differences in the contents of files
and the contents of soft links.  The defaults for the program reflect
this interest.  However sometimes users are also interested in changes
in permissions or ownership.  Alternatively it may happen that a user
is only interested in the set of files whose size changes and changes
to files which keep the same size should be ignored.  To acomidate all
possible uses we gave the user great flexibility in determining what
set of changes are significant.  There is a pick list at the top of
the main screen which displays the current criterion for a difference
to be displayed.  A file which has changes made to properties which
are not picked will not be considered different and will not be
displayed.  Of special note the options:

help	will display the help screen for rpmdiff which contains an
	explanation of how to read the diff format.

all	will require that all differences are considered important.
	This is the same as checking all the boxes of differences

version will display the version of rpmdiff that is being used by
	this webpage.

The organization of the pick list page keeps the total number of
packages hidden from the user.  The pick list page takes a long time
to load because the number of choices is very large.  To save time the
set of package pick lists is not regenerated each time the page is
loaded.  There may have been new packages added to the package
repository since the page was generated and these packages will not be
displayed until the page is regenerated again.  The page will never be
more then one day old.  If you need to use the latest contents of the
package repository check the box at the bottom of the page marked
"Flush Cache" this will increase the loading time of the page but
ensure the freshness of the data.
