# INSTALL
#   gem install watchr
#   cp wtchrspec ~/bin
#   chmod u+x ~/bin/wtchrspec

# Run with: wtchrspec foo.rb
# The test and class need to be in the same file.
# See the walrus destroyallsoftware screencast for an example:
# describe Foo; end
# class Foo; end
# This makes for quick hacking better than writing a huge "main"


# the file passed in as argument 1
FILE=$1
