Just thought i would post a link to this little app.

It's for users that work on OS X machines but also work across multiple platforms. For Example working on .bat files in Text Wrangler and then saving out. Instead of having to keeping clicking the options button to change the line endings you can use this little app to do it. It also works on folders of files and also has a protection setting as well for files that you want to exclude from changing in case it breaks the file.

Works on Leopard and Tiger. I have used on 10.5.6 and works fine.

Here it is:

LineBreak 2.8 software download - Mac OS X - VersionTracker

Hope it helps someone. I needed one of these a while ago.
