### Install package for SFML 2.1 on OS X
###
### Author: Marco Antognini <antognini.marco@gmail.com>
### Date: 26/07/2013
###

### This script install the following:
###
### cmake/          into    /usr/local/share/SFML/cmake/
### doc/            into    /usr/local/share/SFML/doc/
### examples/       into    /usr/local/share/SFML/examples/
### extlibs/        into    /Library/Frameworks/
### Frameworks/     into    /Library/Frameworks/
### include/        into    /usr/local/include/
### lib/            into    /usr/local/lib/
### license.txt     into    /usr/local/share/SFML/
### readme.txt      into    /usr/local/share/SFML/
### templates/      into    /Library/Developer/Xcode/Templates/
###
### It will NOT remove any previous versions.
### Hence, if you have the frameworks of SFML 2.0 installed
### you will keep this runtime (the two verions will be merged).

###
### USAGE
###
### $0 [package]
###
### Package is optional. It represent the path to a package.
### If not present, package is assumed to be $(dirname "$0")
###
### When installing frameworks the script will ask you for
### your password.
