1433	# The targets listed in the the FETCHES target list have the following attributes:
1434	# SOURCES
1435	# INST
1436	# FETCHTOOL
1437	# FETCHFLAGS
1438	# FETCHDIR
1439	# UNPACKTOOL
1440	# UNPACKFLAGS
1441	#
1442	# As usual the target name is an alias for 'creating' the target. Other
1443	# aliases are:
1444	# pass_fetches
1445	# fetch
1446	# unfetch
1447	# download
1448	# unpack
1449	#
1450	# @remark
1451	#
1452	# This is a little bit complex because we must guarantee that if a source file
1453	# changes only sligtly we must refetch it and to a proper unpacking of it. It
1454	# is also a desire that fetched archives and unpacked files can be deleted to
1455	# save space.
1456	#
1457	# Thus, we must be able to cleanup what we've unpacked should any of the
1458	# sources be removed. We do this by maintaining a file listing the files
1459	# and directories that was unpacked. This operation is named 'unfetch'.
1460	#
1461	# We make use of the SIZE and MD5 attributes for each of the sources to
1462	# create a digest that is stored in the primary target file. Subsequent
1463	# runswill compare their digest with it to decide if a refetch is required.
1464	# When a refetch is found necessary, an 'unfetch' is performed first to
1465	# clean out old files and directores. Note even changes in source order
1466	# will cause a refetch due to the way the digest is constructed and
1467	# evaluated.
1468	#
1469	# By not depending directly on the archives (nor on any unpacked files)
1470	# but on a goal made up from the archive name, size and md5, we allow
1471	# the user to delete the archives. Naturally, this means we'll have to
1472	# check and fetch missing archives before attempting to unpack them.
1473	#
1474	# @remark
1475	#
1476	# This feature will NOT work correctly with vanilla GNU make becuase
1477	# it makes use of includedep to avoid too many unnecessary files.
