Bug#666478: upcoming rsvg removal

[Michael Biebl]

Hi everyone,

a few questions have come up since I filed those bugs reports and my bug
description was not fully accurate, I'll try address them with this email.

This is indeed correct. rsvg and rsvg-convert are *not* fully command
line compatbile in one regard. rsvg-convert expects an "-o" parameter
for the output file whereas rsvg doesn't, e.g.

  rsvg inputfile.svg outputfile.png
  rsvg-convert inputfile.svg -o outputfile.png

This is something you need to change when switching from rsvg to
rsvg-convert.

The other parameters (-w,-h,-d,-p,-x,-y,-f) behave the same though.

As I wrote, upstream removed the old rsvg python script. In the Debian
package, I added that symlink to not break existing packages until they
have been updated. When rsvg-convert is called as "rsvg", i.e. via the
symlink, it set's the -o parameter automatically to be fully compatible
with the old rsvg script.

Once all packages have been fixed to use rsvg-convert instead of rsvg, I
will remove rsvg in the next release cycle. I would like to see all
packages being fixed for wheezy, that means the rsvg symlink would be
removed in wheezy+1.

If there are still open questions, please don't hesitate to ask.

Cheers,
Michael
