[Linux-disciples] Setting user and group rights automatically in vim

[Stephen R Laniel]

The blogging package that I use (blosxom) works by grabbing all the files
under a given point in the filesystem tree and displaying them in date
order. One blosxom plugin I use adds metadata to each text file, for
whatever reason. The plugin runs under user www-data, whereas when I
create a new file in vim its user:group is slaniel:slaniel. So the meta
plugin doesn't work unless I manually change the owner on the file. I get
errors like this in my /var/log/apache/error.log:

/*
Unable to update date meta-tag on /home/slaniel/public_html/blosxom/posts_and_data/politics_and_policy/bush_war_on_terror_iraq_etc.txt
*/

So: is there any way to configure vim so that whenever it creates a new
file under a specific path, it creates that file with a specific user,
group, and permissions?
