-# This script is a wrapper to the other download helpers.
-# Its role is to ensure atomicity when saving downloaded files
-# back to BR2_DL_DIR, and not clutter BR2_DL_DIR with partial,
-# failed downloads.
-#
-# Call it with:
-#   $1: name of the helper (eg. cvs, git, cp...)
-#   $2: full path to the file in which to save the download
-#   $*: additional arguments to the helper in $1
-# Environment:
-#   BUILD_DIR: the path to Buildroot's build dir
-
-# To avoid cluttering BR2_DL_DIR, we download to a trashable
-# location, namely in $(BUILD_DIR).
-# Then, we move the downloaded file to a temporary file in the
-# same directory as the final output file.
-# This allows us to finally atomically rename it to its final
-# name.
-# If anything goes wrong, we just remove all the temporaries
-# created so far.
-
-# We want to catch any unexpected failure, and exit immediately.

-# permission bits they want (although we're only really interested in
-# the executable bit.)

-# users (e.g. on a build server), where all users may write to the shared
-# location, since other users would not be allowed to read the files
-# another user downloaded.
-# So, we restore the 'go' access rights to a more sensible value, while
-# still abiding by the current user's umask. We must do that before the
-# final 'mv', so just do it now.
-# Some helpers (cp and scp) may create executable files, so we need to
-# carry the executable bit if needed.

-# if it is unable to open it with O_WRONLY|O_TRUNC; see:
-#   http://pubs.opengroup.org/onlinepubs/9699919799/utilities/cp.html
-# Since the destination filesystem can be anything, it might not support
-# O_TRUNC, so 'cp' would unlink it first.
