+# 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:
+#*~
+#\#*
+#.\#*
