#
# Builds the workspace in debug mode and creates symlinks in ~/.local/bin
# so you can run `coast-dev` and `coastd-dev` directly from any terminal.
#
# Usage:
#   ./dev_setup.sh          # build debug + symlink
#   ./dev_setup.sh --release  # build release + symlink
#
# After running this, add ~/.local/bin to your PATH if it isn't already:
#   export PATH="$HOME/.local/bin:$PATH"
