### pigpiod
`pigpiod` is a script that allows to run pigpiod as a Linux service with root privileges.
The advantage of running pigpiod as a service is that pigpiod can be automatically launched on system startup.
To automatically start pigpiod as a service, do the following:
+ Copy `pigpiod` from this directory to `/etc/init.d/`.
+ Make it executable:
```
sudo chmod +x /etc/init.d/pigpiod
```
+ Tell update-rc.d to automatically start the pigpiod service on system startup:
```
sudo update-rc.d pigpiod defaults
```
+ Now, you can start, stop, and restart pigpiod using
```
sudo service pigpiod start
sudo service pigpiod stop
sudo service pigpiod restart
```
### Findpigpio.cmake
`Findpigpio.cmake` is a script used by CMake to find out where the pigpio header and library files are located.
