== Description

The script manages NuoDB gems, installing them or uninstalling them, removing some
of the command line complexity from developers eyes.

== Mac Only Notes

The dylib for NuoDB must have an @rpath set on Mac, so if you find that the dylib
id is incorrect, you will need to run the install_name_tool to fix it. To see what
the current id is run this command:

  otool -L libNuoRemote.dylib

Incorrect output will look like this:

  libNuoRemote.dylib:
    /Users/build/bamboo-agent-home/xml-data/build-dir/MASTER-PACKAGE-MACOSX/Remote/Debug/libNuoRemote.dylib (compatibility version 0.0.0, current version 0.0.0)
    /usr/lib/libstdc++.6.dylib (compatibility version 7.0.0, current version 52.0.0)
    /usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 159.0.0)

Correct output will look like this:

  libNuoRemote.dylib:
    @rpath/libNuoRemote.dylib (compatibility version 0.0.0, current version 0.0.0)
    /usr/lib/libstdc++.6.dylib (compatibility version 7.0.0, current version 52.0.0)
    /usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 159.0.0)

As necessary, to fix the id you'd run this command:

  install_name_tool -id @rpath/libNuoRemote.dylib libNuoRemote.dylib
