# Specify the gcc executable you will use the dragonegg plugin with either here
# or on the command line, for example like this (replace gcc-4.7 with the gcc
# you want to load the plugin into):
# GCC=gcc-4.7 make ...

# used to build it.

# Specify the copy of LLVM you will build the plugin against by giving its
# llvm-config here or on the command line. To use an installed copy of LLVM,
# specify the installed llvm-config (just 'llvm-config' is enough if it is in
# your path). It is not necessary to install LLVM to build dragonegg against
# it. Instead you can do an LLVM build and point LLVM_CONFIG to the copy of
# llvm-config that was created during the build.
