# Description
# This script installs a browser-interface to control the RPi Cam. It can be run
# on any Raspberry Pi with a newly installed raspbian and enabled camera-support.
#
# Edited by jfarcher to work with github
# Edited by slabua to support custom installation folder
# Additions by btidey, miraaz, gigpi 


# Configure below the folder name where to install the software to,
#  or leave empty to install to the root of the webserver.
# The folder name must be a subfolder of /var/www/ or /var/www/html/ which will be created
#  accordingly, and must not include leading nor trailing / character.
# Default upstream behaviour: rpicamdir="" (installs in /var/www/ or /var/www/html)
