# HOWTO USE:
# ==========

# The script needs three arguments. The first argument to the script is the
# location of the directory where all the tar packages are. This will most
# probably be the directory of this script. The second argument is the location
# of the directory where in this script can compile the programs. The last
# argument is the output directory where all the binaries will be copied to. 
# 
# For example, if the compile_binaries directory is under the home directory, the 
# following can be executed:
# 
# PACK_DIR=$HOME/compile_binaries
# COMPILE_DIR=$HOME/scratch
# OUTPUT_DIR=$HOME/output
# mkdir -p $COMPILE_DIR $OUTPUT_DIR
# /bin/bash $PACK_DIR/compile_binaries.bash $PACK_DIR $COMPILE_DIR $OUTPUT_DIR
#
# The output binaries will be located in $OUTPUT_DIR.
