Simple `zsh` shell script for building the Defold Engine

defbuild

#!/bin/zsh

# `defbuild` is a quick and simple zsh shell script for rebuilding the stuff the
# Defold editor depends on. It will rebuild the engine runtime, Bob, and the
# builtins, and then run `lein init` so the updated dependencies are available
# to the editor.
#
# Usage:
# ```
# cd defold
# ./scripts/build.py shell
# defbuild
# ```
# This rebuilds the engine runtime, Bob, and the builtins. Optionally, a mode
# parameter can be specified to control what gets built.
#
# ```
# defbuild full
# ```
# Cleans the `DYNAMO_HOME` directory, runs `install_ext`, and `install_sdk`
# before proceeding with the build.
#
# ```
# defbuild bob
# ```
# Only rebuilds Bob. Useful when you've made changes to Bob, but not the engine.
