2.1	The directory where FML creates archives

	$ARCHIVE_DIR = 'var/archive'; (default is 'var/archive')


The search path for archive directories is @ARCHIVE_DIR. 
$ARCHIVE_DIR is set to $ARCHIVE_DIR[0].

2.2	Archive Unit


The unit of packing articles to one file is 

	$ARCHIVE_UNIT 


If not defined, FML uses

	$DEFAULT_ARCHIVE_UNIT (default 100)


2.3	get command and search path


Consider "get 1", "mget 1" command.  The search path when FML
interprets "get" and "mget" command follows:

* Case: "get 1" and "mget 1"

1	$SPOOL_DIR (=> $FP_SPOOL_DIR)

2	@ARCHIVE_DIR


	If e.g. var/archive/100.tar.gz is found, FML extracts the
	article 1 from it and send back the article.

* Case: "mget 1-10"  command


The search path algorithm is the same. If plain article are not found
in spool and 100.tar.gz is found, FML extracts 1-10 articles from it
and send back them.

* Case: "get 100.tar.gz" and "mget 100.tar.gz"  command


send back var/archive/100.tar.gz itself ("uuencode"d in default).


2.4	Re-create summary file when expire

	$EXPIRE_SUMMARY = 1;


to re-create summary. This process removes older articles entries in
summary.
