# this script installs the development environment for qt4.8
# qt 5 seems to be targeted at accelerated hardware, which the AM1808 does not have
# additionally, the install for qt5 requires some extra work (and potentially debugging)
# in the future we may get an accelerated hardware chip and the install for qt5 may become
# more supported.  It appears that porting applications from 4.8 to 5.0 is relatively straightforward

# syntax: ./build_qt.py [/path/to/sshfs]
