# This is a helper script to launch Terraform inside the "dlv" debugger,
# configured to await a remote debugging connection on port 2345. You can
# then connect to it using the following command, or its equivalent in your
# debugging frontend of choice:
#    dlv connect 127.0.0.1:2345
#
# This tool does not install dlv. To install it, see its instructions:
#    https://github.com/derekparker/delve/tree/master/Documentation/installation
#
# For more convenient use, you may wish to put this script in your PATH:
#    ln -s ../src/github.com/hashicorp/terraform/scripts/debug-terraform $GOPATH/bin/debug-terraform
#
# Note that when running this script the Terraform binary is NOT in $GOPATH/bin,
# so any providers installed there won't be found unless Terraform searches
# there for some _other_ reason.
