images not picked up when making source releases of Sage 4.3.alpha0 and 4.3.alpha1

You get those two lines with the exclamation marks because the file
MANIFEST.in in Sage 4.3.alpha0 isn't configured to pick up those two
image files. When ticket #7190 (French translation: A Tour of Sage)
[1] was merged in Sage 4.3.alpha0, the file
devel/sage-main/MANIFEST.in wasn't also changed to take into account
the new image files, so these are not picked up when releasing the
alpha0 tarball. A result is that one would not see the image files in
devel/sage-main/doc/fr/a_tour_of_sage. You can fix the missing files
problem as follows:

[mvngu@sage sage-4.3.alpha0-7473-sphinx]$ cd devel/sage-main/
[mvngu@sage sage-main]$ hg st
! doc/fr/a_tour_of_sage/eigen_plot.png
! doc/fr/a_tour_of_sage/sin_plot.png
[mvngu@sage sage-main]$ hg revert -a
reverting doc/fr/a_tour_of_sage/eigen_plot.png
reverting doc/fr/a_tour_of_sage/sin_plot.png
[mvngu@sage sage-main]$ hg st
<no output>

This missing files problem is due to #7190.

based on Sage 4.3.alpha1

Here are some steps to fix the problem with missing image files. On a freshly compiled Sage 4.3.alpha1 or a newly unpacked binary of that version, do a Mercurial revert to recover the deleted images:

[mvngu@sage sage-4.3.alpha1-7606-images]$ cd devel/sage-main/
[mvngu@sage sage-main]$ hg st
! doc/fr/a_tour_of_sage/eigen_plot.png
! doc/fr/a_tour_of_sage/sin_plot.png
[mvngu@sage sage-main]$ hg revert -a
reverting doc/fr/a_tour_of_sage/eigen_plot.png
reverting doc/fr/a_tour_of_sage/sin_plot.png
[mvngu@sage sage-main]$ hg st
<no output>

Next, apply the patch trac_7606-manifest.patch, which configures MANIFEST.in to pick up those two image files when making a source release. Afterwards, making a source tarball with "./sage -sdist <version-number>" should also pick up the two image files.

Looks good to me.
