# CCache + multicore compilation script
# For "The OTX Server"

# Example:
# # make clean
# # time ./build.sh

# Gives:
# real	3m27.070s
# user	6m4.066s
# sys	0m16.659s

# CCACHE recompile (from scratch):
# # make clean
# # time ./build.sh

# Gives:
# real	0m27.620s
# user	0m43.744s
# sys	0m4.766s

# 1/7 of the original compile time!
# When more you do it, more ccache will cache, default is limited to use 1GB storage
