I saw the description of my program paps in the guix database which sais:
"Paps reads a UTF-8
encoded file and generates a PostScript language rendering of the file.
The rendering is done by creating outline curves through the Pango ft2 backend."
This is no longer true for the 0.7.1 version. A more accurate description would be:
"Paps reads a UTF-8 encoded file and generates a pdf file or PostScript rendering of the file through the pango cairo backend"
Cheers,
