# Builds depositspend.wasm contract
# Contracts may link to either:
#   * eosio-contract-simple-malloc: This library builds contracts with
#     small and fast memory allocation. free() is a no-op. Most contracts
#     should use this option.
#   * eosio-contract-full-malloc: This library builds contracts with
#     full memory allocation and reuse. Using this in your contract may
#     help expose memory bugs that eosio-contract-simple-malloc hides.
#     The downsides of eosio-contract-full-malloc are that contracts
#     will be larger and slower.

# Builds depositspend-debug.wasm
#
# This is like depositspend.wasm, but includes debugging information.
# Debug contracts can't normally be installed on chains using `set code`.
# Instead, cltester loads them using its `-s/--subst` option.
#
# Create a debugging contract by linking to either
# eosio-contract-simple-malloc-debug or eosio-contract-full-malloc-debug.

# Generate depositspend.abi
# This is a 2-step process:
#   * Build depositspend.abi.wasm. This must link to eosio-contract-abigen.
#   * Run the wasm to generate the abi

# (shows stack traces on failure).
