Handling Services
TODO SECTION
This section describe the (correct) way to handling services, such as starting, stoping, restarting, etc. SME is different compared with other linux distributions, so service are handled in a different maner.
General handling
sv t servicename
service servicename action
Apache Service
Restarting:
sv t httpd-e-smith
service httpd restart
