## Potential features
#
# 1) [X] Reset password for a user
#	Format is password+salt:salt
# 2) [X] Backup Database --> Look in to using Expect to enter password correctly when it contains od characters.
# 3) [X] Clear cache --> cache/; find -type f -exec rm {} \;
# 4) [X] Look up list of users
#	select * from ${prefix}users
# 5) [X] Swap admin user
# 6) [X] Summarize version and connection info
# 7) [X] Print out MySQL credentials
# 8) [X] Enable/Disable Cache
# 9) [X] Enable/Disable Gzip
# 10 [ ] Enable memcache: http://www.siteground.com/tutorials/supercacher/joomla_memcached.htm
# 11 [ ] Create a copy function to create dev sites
# sudo -u $(getusr) -- siteworx -u -n -c MysqlDb -a add --name $newDB --create_user 1 --user $newUser --password $dbpass --confirm_password $dbpass
# mysqldump -u'$dbuser' -p'$dbpass' $dbname | pv | mysql -u'$newUser' -p'$dbpass' $newDB
# rsync -a source/dir/ dest/dir/
