If you installed with an rpm you can use 'rpm -q -V packagename' to
check that files haven't changed since the install.

If you have a master copy on some other server, you can  use 'rsync
-avn  --delete dir  user at production_host:/path/above/dir' to see a
list of files with differences.  And if you remove the n from the
arguement list it will fix any differences (but be very sure you are
in the right place if you use --delete without -n).

Ultimately, you should probably be using subversion or git to maintain
this master copy. If you only have one or a few production servers you
can just use the version control tools to update them directly, but I
prefer a staging copy where you can test the changes before rsyncing
to production.
