# Release profile is optimized for output size. only "questionable" one is the
# panic setting imo, it kills the backtrace but reduces huge binary sizes
#
# a basic clap binary goes from about 1MiB to about 600k, so... seems worth it
#
# Most of the "bloat" here is going to be .text being format strings and whatnot.
# Example:
# $ nix-shell -p cargo -p cargo-bloat --run 'cargo bloat --release'
