+# How to suppress comments when performing `git diff` on `.po` files. 
+
+*Taken from: http://stackoverflow.com/questions/2006351/gettext-po-files-under-version-control*
+
+Changes in the codebase can alter line numberings given in `.po` 'comments'. 
+While such changes should be committed they make obsecure the actual
+translation changes made, and make auditing them difficult.
+
+1. Create `/usr/local/bin/strippocomments` as given in this gist.
+
+2. Set up pre-processing of .po files by editing `.git/info/attributes` and adding:
+
+        *.po diff=podiff
+
+3. Edit `.git/config` and add the line
+
+        [diff "podiff"]
+            textconv = /usr/local/bin/strippocomments
