directories.
(org-publish-get-base-files-1): Fix :recursive parameter ignoring
extension restriction.

"htlatex" (or path to said) to enable svg generation from latex code
blocks.

svg generation.
(org-babel-execute:latex): Generate SVG images directly from latex
code blocks (assumes tikz).

building citation list.

* org.el (org-refile): With a numeric prefix argument of `3',
emulate (setq org-refile-keep t) and copy the subtree to the
target location, don't delete it.
* org.texi (Refile and copy): Document `C-3 C-c C-w' and add
an index entry for `org-refile-keep'.
* org.el (org-set-regexps-and-options-for-tags): Fix the
setting of tag groups when relying on `org-tag-alist', not on
tags directly set in the buffer with the #+TAGS option.
Thanks to Maurice for reporting this.
* lisp/org-element.el (org-element-item-interpreter): Correctly
interpret back plain lists with "*" items. This fixes "This is not
a list" error returned in this case.

* org.el (org-forward-element, org-backward-element): Throw a
message instead of an error when trying to move from a
