"""Fix permissions on theargentimes.com website.
Due to a legal dispute, the staff of theargentimes.com had FTP access
to their web site, but not shell access. The web host was configured
such that PHP files that aren’t executable would refuse to
run. Unfortunately, upgrading WordPress results in replacing existing
.php files with other, non-executable .php files.
So this program walks the directory tree looking for non-executable
.php files and issues a nonstandard 'chmod 755' command over the FTP
connection, which the web host's FTP daemon happened to accept.
