;;; Commentary:
;;
;; This library implements a KOMA Scrlttr2 back-end, derived from the
;; LaTeX one.
;;
;; Depending on the desired output format, three commands are provided
;; for export: `org-koma-letter-export-as-latex' (temporary buffer),
;; `org-koma-letter-export-to-latex' ("tex" file) and
;; `org-koma-letter-export-to-pdf' ("pdf" file).
;;
;; On top of buffer keywords supported by `latex' back-end (see
;; `org-latex-options-alist'), this back-end introduces the following
;; keywords:
;; - "CLOSING" (see `org-koma-letter-closing'),
;; - "FROM_ADDRESS" (see `org-koma-letter-from-address'),
;; - "LCO" (see `org-koma-letter-class-option-file'),
;; - "OPENING" (see `org-koma-letter-opening'),
;; - "PHONE_NUMBER" (see `org-koma-letter-phone-number'),
;; - "SIGNATURE" (see `org-koma-letter-signature')
;; - "PLACE" (see `org-koma-letter-place')
;; - and "TO_ADDRESS". If unspecified this is set to "\mbox{}".
;;
;; TO_ADDRESS and FROM_ADDRESS can also be specified using heading
;; with the special tags specified in
;; `org-koma-letter-special-tags-in-letter', namely "to" and "from".
;; LaTeX line breaks are not necessary if using these headings. If
;; both a headline and a keyword specify a to or from address the
;; value is determined in accordance with
;; `org-koma-letter-prefer-special-headings'.
;;
;; A number of OPTIONS settings can be set to change which contents is
;; exported.
;; - backaddress (see `org-koma-letter-use-backaddress')
;; - foldmarks (see `org-koma-letter-use-foldmarks')
;; - phone (see `org-koma-letter-use-phone')
;; - email (see `org-koma-letter-use-email')
;; - place (see `org-koma-letter-use-place')
;; - subject, a list of format options
;; (see `org-koma-letter-subject-format')
;; - after-closing-order, a list of the ordering of headings with
;; special tags after closing (see
;; `org-koma-letter-special-tags-after-closing') -
;; after-letter-order, as above, but after the end of the letter
;; (see `org-koma-letter-special-tags-after-letter').
;;
;; The following variables works differently from the main LaTeX class
;; - "AUTHOR": default to user-full-name but may be disabled. (see org-koma-letter-author),
;; - "EMAIL": same as AUTHOR, (see org-koma-letter-email),
;;
;; Headlines are in general ignored. However, headlines with special
;; tags can be used for specified contents like postscript (ps),
;; carbon copy (cc), enclosures (encl) and code to be inserted after
;; \end{letter} (after_letter). Specials tags are defined in
;; `org-koma-letter-special-tags-after-closing' and
;; `org-koma-letter-special-tags-after-letter'. Currently members of
;; `org-koma-letter-special-tags-after-closing' used as macros and the
;; content of the headline is the argument.
;;
;; Headlines with two and from may also be used rather than the
;; keyword approach described above. If both a keyword and a headline
;; with information is present precedence is determined by
;; `org-koma-letter-prefer-special-headings'.
;;
;; You will need to add an appropriate association in
;; `org-latex-classes' in order to use the KOMA Scrlttr2 class.
;; The easiest way to do this is by adding
;;
;; (eval-after-load "ox-koma-letter"
;; '(org-koma-letter-plug-into-ox))
;;
;; to your init file. This will add a very sparse scrlttr2 class and
;; set it as the default `org-koma-latex-default-class'. You can also
;; add you own letter class. For instace:
;;
;; (add-to-list 'org-latex-classes
;; '("my-letter"
;; "\\documentclass\[%
;; DIV=14,
;; fontsize=12pt,
;; parskip=half,
;; subject=titled,
;; backaddress=false,
;; fromalign=left,
;; fromemail=true,
;; fromphone=true\]\{scrlttr2\}
;; \[DEFAULT-PACKAGES]
;; \[PACKAGES]
;; \[EXTRA]"))
;;
;; Then, in your Org document, be sure to require the proper class
;; with :
;;
;; #+LATEX_CLASS: my-letter
;;
;; Or by setting `org-koma-letter-default-class'.

If narrowing is active in the current buffer, only export its
narrowed part.
If a region is active, export that region.
A non-nil optional argument ASYNC means the process should happen
asynchronously. The resulting file should be accessible through
the `org-export-stack' interface.
When optional argument SUBTREEP is non-nil, export the sub-tree
at point, extracting information from the headline properties
first.
When optional argument VISIBLE-ONLY is non-nil, don't export
contents of hidden elements.
When optional argument BODY-ONLY is non-nil, only write code
between \"\\begin{letter}\" and \"\\end{letter}\".
EXT-PLIST, when provided, is a property list with external
parameters overriding Org default settings, but still inferior to
file-local settings.
Return PDF file's name."
