## FILENAME:    arduino.nanorc
##
## DESCRIPTION: The arduino.nanorc syntax files allows syntax highlighting
##              for Arduino sketch files in the GNU nano text editor.

## COMMENTS:    -Most of the code was taken from the c.nanorc code found with 
##               GNU nano 2.2.6.
##              -Direction was taken from the arduino vim syntax code by johannes
##               <https://bitbucket.org/johannes/arduino-vim-syntax/>
##              -Tested on Ubuntu Server 11.04 Natty Narwhal and GNU nano 2.2.6
##
## DIRECTIONS:  For Ubuntu Server 11.04 Natty Narwhal:
##              -Move this file <arduino.nanorc> to the nano directory
##               /usr/share/nano/
##              -Add arduino.nanorc reference to the nanorc settings file
##               /etc/nanorc
##               ...
##               ## Arduino
##               /usr/share/nano/arduino.nanorc
##               ...

## String highlighting.  You will in general want your brightblacks and
## strings to come last, because syntax highlighting rules will be
## applied in the order they are read in.
