;;; 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',
;;   - URL: see `org-koma-letter-url',
;;   - FROM_LOGO: see `org-koma-letter-from-logo',
;;   - SIGNATURE: see `org-koma-letter-signature',
;;   - PLACE: see `org-koma-letter-place',
;;   - LOCATION: see `org-koma-letter-location',
;;   - TO_ADDRESS:  If unspecified this is set to "\mbox{}".
;;
;; TO_ADDRESS, FROM_ADDRESS, LOCATION, CLOSING, and SIGNATURE can also
;; be specified using "special headings" with the special tags
;; specified in `org-koma-letter-special-tags-in-letter'.  LaTeX line
;; breaks are not necessary for TO_ADDRESS, FROM_ADDRESS and LOCATION.
;; If both a heading 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')
;;   - url (see `org-koma-letter-use-url')
;;   - from-logo (see `org-koma-letter-use-from-logo')
;;   - email (see `org-koma-letter-use-email')
;;   - place (see `org-koma-letter-use-place')
;;   - location (see `org-koma-letter-use-location')
;;   - 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 also `org-koma-letter-author'),
;;   - EMAIL: Same as AUTHOR. (see also `org-koma-letter-email'),
;;
;; FROM_LOGO uses LaTeX markup.  FROM_LOGO provides the
;; "includegraphics" command to tell LaTeX where to find the logo.
;; This command needs to know the logo's directory and file name.  The
;; directory can either be relative or absolute, just as you would
;; expect.  LaTeX can use three file types for the logo: PDF, JPEG, or
;; PNG.  The logo can either include or exclude its extension, which
;; might surprise you.  When you exclude its extension, LaTeX will
;; search the directory for the "best" quality graphics format.  For
;; example if it finds both logo.pdf and logo.png then it will
;; identify the PDF as "better", and include "logo.pdf".  This can be
;; useful, for example, when you are mocking up a logo in the PNG
;; raster format and then switch over to the higher quality PDF vector
;; format.  When you include the file extension then LaTeX will
;; include it without searching for higher quality file types.
;; Whatever file type you choose, it will probably require a few
;; design iterations to get the best looking logo size for your
;; letter.  Finally, the directory and file name are specified
;; *without* quotes.  Here are some examples with commentary, in the
;; location of your letter, with a logo named "logo", to get you
;; started:
;;
;;   Logo in the same directory: \includegraphics{logo}
;;       or a sub-directory:     \includegraphics{logos/production/logo}
;;
;;   Logos specified using absolute paths on Linux or Windows:
;;
;;       \includegraphics{~/correspondence/logo}
;;       \includegraphics{~/correspondence/logos/production/logo}
;;       \includegraphics{c:/you/correspondence/logo}
;;       \includegraphics{c:/you/correspondence/logos/production/logo}
;;
;;   Logos in the same directory where the "better" quality PDF will
;;   be chosen over the JPG:
;;
;;       \includegraphics{logo.pdf}
;;       \includegraphics{logo.png}
;;
;; Headings are in general ignored.  However, headings 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 heading is the argument.
;;
;; Headings with to and from may also be used rather than the keyword
;; approach described above.  If both a keyword and a heading with
;; information is present precedence is determined by
;; `org-koma-letter-prefer-special-headings'.
;;
;; You need an appropriate association in `org-latex-classes' in order
;; to use the KOMA Scrlttr2 class.  By default, a sparse scrlttr2
;; class is provided: "default-koma-letter".  You can also add you own
;; letter class.  For instance:
;;
;;   (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'.
;;
;; You may have to load (LaTeX) Babel as well, e.g., by adding
;; it to `org-latex-packages-alist',
;;
;;    (add-to-list 'org-latex-packages-alist '("AUTO" "babel" nil))

;;; Code:

(require 'cl-lib)
(require 'ox-latex)

;; Install a default letter class.
