# I deliberately didn't DRY /usr/local references into a variable as this | |
# script will not "just work" if you change the destination directory. However | |
# please feel free to fork it and make that possible. | |

# If you do fork, please ensure you add a comment here that explains what the | |

# 15th May 2010: | |
# Noticed that on a fresh install of 10.6 the default group for | |
# Administrators is admin not staff. In fact no users are in staff so | |
# replaced all references to staff with admin. Tested on 10.6.3. | |
# | |
# 30th March 2010: | |
# Added a check to make sure user is in the staff group. This was a problem | |
# for me, and I think it was due to me migrating my account over several | |
# versions of OS X. I cannot verify that for sure, and it was tested on | |
# 10.6.2 using the Directory Service command line utility and my laptop. | |
# | |
# My assumptions are: | |
# - you are running OS X 10.6.x | |
# - your machine is not managed as part of a group using networked | |
# Directory Services | |
# - you have not recently killed any baby seals or kittens | |
# | |
# 14th March 2010: | |
# Adapted CodeButler's fork: http://gist.github.com/331512 | |

you please; please refer to the website. If you still want to use this script | |
