# Makefile_evio

# Builds EVIO under a new directory rooted in the current working
# directory. The new directory (DIR_NAME) has a name that depends on
# the version being built.

# EVIO_VERSION defines which tagged version to build. It should
# correspond to the name of the desired directory in the repos/tags
# directory of the repository. If left undefined, the latest version
# will be checked out from the repos/trunk.
