If you just want to create pdf or don't mind getting a different theme for the pdf, you could also use one these:
http://pypi.python.org/pypi/rst2beamer/0.6.6
http://pypi.python.org/pypi/rst2odp/0.2.3
http://web.archive.org/web/20130718071252/http://lateral.netmanagers.com.ar/stories/BBS52.html
It is also possible to theme these to get the same theme as for the S5 presentation, but it takes a bit more work. I'm currently using rst2pdf with my own custom theme.
The latter link, for example, suggests using the following commandline:
rst2pdf slides.txt -b1 -s slides.style
with slides.style containing:
{"pageSetup": {
"width": "16cm",
"height": "9cm",
"margin-top": "0cm",
"margin-bottom": "0cm",
"margin-left": "0cm",
"margin-right": "0cm",
"margin-gutter": "0cm",
"spacing-header": "5mm",
"spacing-footer": "5mm",
"firstTemplate": "cutePage"
},
"pageTemplates" : {
"cutePage": {
"frames": [
["10%", "10%", "80%", "80%"]
],
"background" : "background.svg"
}
}
}
