I'll comment. I am the one who told that to David. I have shamelessly sat
on this info for about 3 years. I noticed it when I first tried to package
sympow for Gentoo as part of my sage porting drive. At the time I had to
allow the directory where the sympow scripts are installed to be world
writable....
That no one really noticed means that no one using a global sage install
has been using sympow for their work. The only people using it must have
used a private installation. We now have a fix for this problem in sage-
on-gentoo, Christopher, the other sage-on-gentoo dev, has figured a way of
getting sympow to write in $HOME/.sympow in the last month or so.
I think there is a case for trying to replace sympow. It seems like the
original author has abandoned it - the sympow homepage has gone. Sage
could become sympow
upstream. But given the quality of the code there is a high burden for
maintenance. It probably would be more beneficial in the long run to
rewrite the functionality altogether. Given that there are references I
think it could be a nice student project.
That's my opinion.
