Look at it here: http://pzwart3.wdka.hro.nl/~egreenhalgh/urllib/socialistScrape1.html Scrapes slogans & displays them to the user in the browser. Will eventually have a 'print' button to generate a pdf file.

making PDFs
Anyone know a good way of making nice looking pdfs?
The internets suggested making a .ps file and using Ghostscript's ps2pdf function to convert to .pdf.
generate a .ps file
This contains instructions on fonts etc.
%!
/Helvetica findfont 300 scalefont setfont
300 300 moveto
(Hello, world!) show
showpage
convert to .pdf
In bash, do something like this:
ps2pdf test.ps test.pdf
This also works:
find . -type f -name "*.ps" | while read ONELINE; do ps2pdf "$ONELINE" "$(echo "$ONELINE" | sed 's/.ps/.pdf/g')"; done
example of browser-based pdf generation
Go here, click link, get your custom placard: http://pzwart3.wdka.hro.nl/~egreenhalgh/cgi-bin/urllib/scrapedPlacards/socialistScrapePdf.cgi
(not working atm because www-data not able to write files - asked evo to change permissions.)
