Spreading .gitignore rules to svn:ignore and keeping them in sync

[Marcelo de Moraes Serpa <celoserpa@gmail.com>]

Hello list,

I'm working on a project that is using svn as it's
vesion-tracking/control technology. I'm the only rebel and I'm using
git-svn to interact with this svn repo :)

I need to make the version control system ignore a specific file and
spread this ignore rule across all developers. Now, if everyone was
using git, this would be a simple solution -- just create a .gitignore
file in the root of the working tree and commit it. The thing is, all
other developers are using svn, and I'm not sure how I could put this
entry into svn:ignore for them and also make my .gitignore synced with
svn:ignore.

Any ideas?

Thanks in advance,
