# ------------------------------------------------------------------------------
# lua-mpi build instructions
# ------------------------------------------------------------------------------
#
# 1. Make sure you have the MPI sources installed.
#
# 2. Create a file called Makefile.in which contains macros like these:
#
#    CC = mpicc
#    LUA_HOME = /path/to/lua-5.2.1
#
#    # Additional compile flags are optional:
#
#    CFLAGS = -Wall -O2
#    LVER = lua-5.2.1 # can be lua-5.1 or other
#
#
# 3. Optionally, you may install local Lua sources by typing `make lua`.
#
#
# 4. Run `make`.
#
# ------------------------------------------------------------------------------
