Q:

How to deal with Icon@2x.png in svn? 

I want to check in my icons and other PNGs.  Of course, I'm following the iPhone image naming convention, so I have Icon.png, and Icon@2x.png, Default.png and Default@2x.png. 
One problem: svn thinks I'm trying to add something with a pinned version. 
hacksaw > svn add Default@2x.png
svn: warning: 'Default' not found

hacksaw > ls -l Default@2x.png
-rw-r--r--@ 1 hacksaw  hacksaw  11139 Mar  1 14:44 Default@2x.png

Is there an alternate syntax for the 2x file?  Or is there an escape that svn uses that I can't seem to find in the red-bean book? 
I've thought about switching to git, but I'd really like to put it off until I finish this submission.

How to Add Those @2x iOS4 Resources to SVN
$ svn add Default@2x.png@
A (bin) Default@2x.png

A:

You need to append '@' to any filename that already contains '@', e.g. svn add "Default@2x.png@". 
If you want to add lots of files containing '@', and you're using bash or similiar, the following snippet is very handy:
for i in '*@*'; do svn add "$i@"; done
