# - Export packaging directory in $PKG.
# - Add (pre|post)-(configure|build|install) instructions.
# - Have some instructions be non-critical, like the (pre|post] ones.
# - Be careful about return values, flee from everything if something
# goes somehow wrong.
# - Make things thread-safe. (those ENV[]= calls are definitely not)
