A simple shell script to mount a SparkleShare DiskImage on a Mac and start the SparkleShare application

mount_sparkle.sh

#!/bin/bash -x

# Precondition:
# SparkleShare folder is located into a Mac Sparse Bundle that
# must be mounted before SparkleShare is started
# the user who runs this script needs to get permissions to
# to delete a directory in  /Volumes. Therefore sudo is used
# entry in /etc/sudoers:
# %users  ALL=(All) NOPASSWD:/bin/rm -rf /Volumes/Sparkle


# where is your SparkleBundle located?
