(defconst org-archive-tag "ARCHIVE"
  "The tag that marks a subtree as archived.
An archived subtree does not open during visibility cycling, and does
not contribute to the agenda listings.")
(defcustom org-archive-location "%s_archive::"
  "The location where subtrees should be archived.

The value of this variable is a string, consisting of two parts,
separated by a double-colon.  The first part is a filename and
the second part is a headline.

When the filename is omitted, archiving happens in the same file.
%s in the filename will be replaced by the current file
name (without the directory part).  Archiving to a different file
is useful to keep archived entries from contributing to the
Org Agenda.

The archived entries will be filed as subtrees of the specified
headline.  When the headline is omitted, the subtrees are simply
filed away at the end of the file, as top-level entries.  Also in
the heading you can use %s to represent the file name, this can be
useful when using the same archive for a number of different files.

Here are a few examples:
\"%s_archive::\"
	If the current file is Projects.org, archive in file
	Projects.org_archive, as top-level trees.  This is the default.

\"::* Archived Tasks\"
	Archive in the current file, under the top-level headline
	\"* Archived Tasks\".

\"~/org/archive.org::\"
	Archive in file ~/org/archive.org (absolute path), as top-level trees.

\"~/org/archive.org::* From %s\"
	Archive in file ~/org/archive.org (absolute path), under headlines
        \"From FILENAME\" where file name is the current file name.

\"~/org/datetree.org::datetree/* Finished Tasks\"
        The \"datetree/\" string is special, signifying to archive
        items to the datetree.  Items are placed in either the CLOSED
        date of the item, or the current date if there is no CLOSED date.
        The heading will be a subentry to the current date.  There doesn't
        need to be a heading, but there always needs to be a slash after
        datetree.  For example, to store archived items directly in the
        datetree, use \"~/org/datetree.org::datetree/\".

\"basement::** Finished Tasks\"
	Archive in file ./basement (relative path), as level 3 trees
	below the level 2 heading \"** Finished Tasks\".

You may define it locally by setting an ARCHIVE property.  If
such a property is found in the file or in an entry, and anywhere
up the hierarchy, it will be used.

You can also set it for the whole file using the keyword-syntax:

#+ARCHIVE: basement::** Finished Tasks"
