# Three stages of TINT build system:
#
# 1) generate_core.sh extracts the core part from buildgcc script,
#     most importantly the checksum calculation/verification functions.
#
# 2) tintify_core.sh adds the TINT-specific footer/header to the core,
#     such as the properties of current version including its checksum.
#
# 3) tint.sh - generated and "tintified" core script - builds a TINT.
