# The build output directory listed under EXTRA_DIST contains the files to
# include in the release/source tarball.
#
# It is recommended to use the following command to regenerate the file list
# as files get added/removed:
#
# find . \
#      -mindepth 1 -maxdepth 1 \
#      -not \( -name node_modules -prune \) \
#      -not \( -name *git* -prune \) \
#      -not \( -name *husky* -prune \) \
#      -not \( -name public -prune \) \
#      -not \( -name *[Mm]ake* -prune \) \
#      | sed -E 's@^./(.+)$@\1 \\@'
#
# The find command:
# * ignores ./node_modules directory,
# * ignores git related files,
# * ignores husky related files
# * ignores ./public directory
# * ignores make related files, and
# * removes leading "./" and append "\"
#
# Note: This only works when we want to include all files within the listed
# subdirectories. It is recommended to run a similar find command on a
# subdirectory to skip undesired files in the subdirectory.
