# Xcode 7 (incl. 7.0.1) seems to have a dependency on the system ruby.
# xcodebuild is screwed up by using rvm to map to another non-system
# ruby†. This script is a fix that allows you call xcodebuild in a
# "safe" rvm environment, but will not (AFAIK) affect the "external"
# rvm setting.
#
# The script is a drop in replacement for your xcodebuild call.
#
#   xcodebuild arg1 ... argn
#
# would become
#
#   path/to/xcbuild-safe.sh arg1 ... argn

# This allows you to use rvm in a script. Otherwise you get a BS
# error along the lines of "cannot use rvm as function". Jeez.
