Where can I download the extension?
Searching for "texvc" in the english wikipedia shows me that:

"Like the rest of MediaWiki, it is available under the terms of the GNU GPL from the MediaWiki site."

When I click the link to the MediaWiki site, I can't find anything about a texvc download. If I type "texvc" into the search field, I come to this site. But I can't find a hint how and where I can download the software. 84.134.179.36 21:23, 18 June 2007 (UTC)

How to set permissions on newly rendered png's?
For some security reasons we drive php as cgi-script using suphp. So all the mediawiki stuff is executed under a userid different from wwwrun. Since texvc is started via php, the resulting files are owned by this userid, too. This is nice, but the file permissions of the png-graphics is read/write only for the owner. As the pngs are loaded without php, wwwrun must have read access. I tried to fix this using acls on all the directories containing the math-graphics but with no effect. The resulting files are read/writeable only by the files owner. Any idea how to avoid this?
