-# Have editor/IDE/OS specific files you need to ignore? Consider using a global gitignore: 
-#
-# * Create a file at ~/.gitignore
-# * Include files you want ignored
-# * Run: git config --global core.excludesfile ~/.gitignore
-#
-# After doing this, these files will be ignored in all your git projects,
-# saving you from having to 'pollute' every project you touch with them
-#
-# Not sure what to needs to be ignored for particular editors/OSes? Here's some ideas to get you started. (Remember, remove the leading # of the line)
-#
-# For MacOS:
-#
 .DS_Store
-
-# For TextMate
 *.tmproj
 tmtags
-
-# For emacs:
 *~
 \#*
 .\#*
-
-# For vim:
-*.swp
-
-# For redcar:
+*.sw[p-n]
 .redcar
-
-# For rubinius:
 *.rbc
