# ## Notes

# - We use `bash` so that we can use `pipefail`.

SHELL := bash

# Define shell flags.

# ## Notes

# - `.SHELLFLAGS` was introduced in GNU Make 3.82 and has no effect on the version of GNU Make installed on Mac OS X, which is 3.81.

# - The `-e` flag causes `bash` to exit immediately if a `bash` executed command fails.

# - The `-u` flag causes `bash` to exit with an error message if a variable is accessed without being defined.

# - The `pipefail` option specifies that, if any of the commands in a pipeline fail, the entire pipeline fails. Otherwise the return value of a pipeline is the return value of the last command.

# - The `-c` flag is in the default value of `.SHELLFLAGS`, which must be preserved, as this is how `make` passes the script to be executed to `bash`.

.SHELLFLAGS := -eu -o pipefail -c

# Remove targets if its recipe fails.

# ## Notes

# - Mentioning this target anywhere in a Makefile prevents a user from re-running make and using an incomplete or invalid target.

# - When debugging, it may be necessary to comment this line out so the incomplete or invalid target can be inspected.

# Default target.

# @example

# make

# @example

# make all

# ## Notes

# - The rule uses the following format:

# @example

# make inspect.ROOT_DIR

# @example

# make inspect.CC
