+= How do I remove a file from svn (and all of it's revisions)? =
+
+This page is designed for MFPL administrators. Special permissions are required to execute these steps. If you have a file you would like removed from our subversion repository, please [/newticket open a ticket to request it's removal].
+
+First, check the [ http://subversion.tigris.org/faq.html#removal docs] to see if `svn obliterate` has been implemented. As of this writing, it has not been implemented. 
+
+To manually obliterate a file, follow these steps on `moses.mayfirst.org` (aka `svn.mayfirst.org`). Replace $GROUP with the name of the group whose repo has the file you want to obliterate. 
+
+{{{
+mkdir /srv/backup
+cd /srv/backup
+cp -rp /srv/svn/$GROUP $GROUP.full.backup
+svnadmin dump /srv/svn/$GROUP > $GROUP.dump
+grep "file/or/dir/to/delete" $GROUP.dump # check output for exact path to pass to next command
+cat $GROUP.dump | svndumpfilter exclude path/to/exclude > $GROUP.clean.dump
+grep "file/or/dir/to/delete" mfpl.clean.dump #make sure it's really gone
+mv /home/$GROUP/.ssh/authorized_keys{,.off} # make sure nobody uses the repo
+rm -rf /srv/svn/$GROUP
+svnadmin create /srv/svn/$GROUP
+cp $GROUP.full.backup/hooks/* /srv/svn/$GROUP/hooks/
+svnadmin load /srv/svn/$GROUP < $GROUP.clean.dump
+chgrp -R $GROUP /srv/svn/$GROUP
+find /srv/svn/$GROUP -perm -u+w -exec chmod g+w '{}' ';'
+mv /home/$GROUP/.ssh/authorized_keys{.off,}
+}}}
+
+Note: if you are removing a file or directory from the MFPL repo or any repo that is synchronizing to a trac installation, you need to repeat this process on the repo feeding the trac installation.
+
+Here's a sample output of running these commands on moses, the server running the MFPL trac installation (note - because it's on moses, it's a little different than the commands in the above example which are designed to be run on allende, the svn server). I used the --quiet option so the whole session could be copied with less noise. Also, the initial backup was made earlier in the session.
