Remove contrib/oldexp/.

If users want to use the old exporter, they now need
to checkout an earlier version of Org.
parent 8decdbcd
This directory contains the obsolete libraries for exporting .org
files to various formats.
It is kept here for archiving purpose and to ease the reading of the
source code, in case it helps with users migrating to the new export
engine.
If you want to use the old exporters, you should checkout the maint
branch of Org's repository and reload Org.

;;; Commentary:
;;
;; This is an utility to handle BibTeX export to both LaTeX and html
;; exports. It uses the bibtex2html software from
;; http://www.lri.fr/~filliatr/bibtex2html/
;;
;; The usage is as follows:
;; #+BIBLIOGRAPHY: bibfilebasename stylename optional-options
;; e.g. given foo.bib and using style plain:
;; #+BIBLIOGRAPHY: foo plain option:-d
;;
;; Optional options are of the form:
;;
;; option:-foobar pass '-foobar' to bibtex2html
;; e.g.
;; option:-d sort by date.
;; option:-a sort as BibTeX (usually by author) *default*
;; option:-u unsorted i.e. same order as in .bib file
;; option:-r reverse the sort.
;; see the bibtex2html man page for more. Multiple options can be combined like:
;; option:-d option:-r
;;
;; Limiting to only the entries cited in the document:
;; limit:t
;; For LaTeX export this simply inserts the lines
;; \bibliographystyle{plain}
;; \bibliography{foo}
;; into the tex-file when exporting.
;; For Html export it:
;; 1) converts all \cite{foo} to links to the bibliography
;; 2) creates a foo.html and foo_bib.html
;; 3) includes the contents of foo.html in the exported html file

;;; Commentary:
;;
;; This is a utility for pre-processing blocks in org files before
;; export using the `org-export-preprocess-hook'. It can be used for
;; exporting new types of blocks from org-mode files and also for
;; changing the default export behavior of existing org-mode blocks.
;; The `org-export-blocks' and `org-export-interblocks' variables can
;; be used to control how blocks and the spaces between blocks
;; respectively are processed upon export.
;;
;; The type of a block is defined as the string following =#+begin_=,
;; so for example the following block would be of type ditaa. Note
;; that both upper or lower case are allowed in =#+BEGIN_= and
;; =#+END_=.

;;
;;; Currently Implemented Block Types
;;
;; ditaa :: (DEPRECATED--use "#+begin_src ditaa" code blocks) Convert
;; ascii pictures to actual images using ditaa
;; http://ditaa.sourceforge.net/. To use this set
;; `org-ditaa-jar-path' to the path to ditaa.jar on your
;; system (should be set automatically in most cases) .
;;
;; dot :: (DEPRECATED--use "#+begin_src dot" code blocks) Convert
;; graphs defined using the dot graphing language to images
;; using the dot utility. For information on dot see
;; http://www.graphviz.org/
;;
;; export-comment :: Wrap comments with titles and author information,
;; in their own divs with author-specific ids allowing for
;; css coloring of comments based on the author.
;;
;;; Adding new blocks
;;
;; When adding a new block type first define a formatting function
;; along the same lines as `org-export-blocks-format-dot' and then use
;; `org-export-blocks-add-block' to add your block type to
;; `org-export-blocks'.
