Description:

Some features of Emacs' reStructuredText major mode fail because renaming of rst2* scripts in the Docutils PKGBUILD breaks Emacs rst.el.

Additional info:

The Docutils PKGBUILD contains this:

for f in $pkgdir/usr/bin/*.py; do
mv $f $pkgdir/usr/bin/$(basename $f .py)
done

which renames rst2html.py (and similar scripts) to rst2html (et cetera). I assume this renaming is done for aesthetic reasons.

Unfortunately, the reStructuredText mode file for Emacs (rst.el), which I believe comes from the Docutils project, contains:

(defvar rst-compile-toolsets
'((html . ("rst2html.py" ".html" nil))
(latex . ("rst2latex.py" ".tex" nil))
(newlatex . ("rst2newlatex.py" ".tex" nil))
(pseudoxml . ("rst2pseudoxml.py" ".xml" nil))
(xml . ("rst2xml.py" ".xml" nil))
(pdf . ("rst2pdf.py" ".pdf" nil))
(s5 . ("rst2s5.py" ".xml" nil)))
"An association list of the toolset to a list of the (command to use,
extension of produced filename, options to the tool (nil or a
string)) to be used for converting the document.")

and therefore anything in Emacs that relies on the rst-compile-toolsets variable will fail to work properly, because files with the standard names do not exist.
