# Basically, I just need the following code integrated so that we can optionally pass RakeMate
# some parameters (rather than calling it directly and assuming that the current file is active)
#
# It would also be nice if we could use my method of inheriting the PATH from the environment so
# that Rails users wouldn't have to set TM_RAKE.
#
# Here are two sample calls to my rake_helper (aka, my version of RakeMate):
#
# == 1. Migrate to Current ==
# RUBYLIB="$TM_BUNDLE_SUPPORT/lib:$RUBYLIB"
# "${TM_RUBY:=ruby}" -- "${TM_BUNDLE_SUPPORT}/bin/rake_helper.rb" -t db:migrate -
#
# == 2. Migrate to Version... ==
# RUBYLIB="$TM_BUNDLE_SUPPORT/lib:$RUBYLIB"
#
# Find the current version number from the schema.rb file
# export CURRENT=`grep 'Schema\.define' "$TM_PROJECT_DIRECTORY/db/schema.rb" | \
#   ruby -e 'print $stdin.read.scan(/\d+/).first'`
# 
# "${TM_RUBY:=ruby}" -- "${TM_BUNDLE_SUPPORT}/bin/rake_helper.rb" db:migrate -q \
#   "Migrate to which version? (Current version: $CURRENT)" -v VERSION
