# Makefile_sim-recon

# Builds sim-recon under a new directory (SIM-RECON_DIR) rooted in the current
# working directory. The new directory has a name that depends on the
# version being built.

# SIM-RECON_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.
