 Developers of cross-platform software `make a habit`_ of not relying on case-sensitive filesystem access,
 but this issue still `crops up when porting`_ from Windows to Linux or vice-versa.
 
+For example, the Linux port of the `Unity engine`_ has `issues with case-sensitive filesystems`_.
+
+    Unity does not properly run on a case-sensitive file system (which is something
+    that Unity users have discovered if they’ve tried to install and run Unity on a
+    case-sensitive HFS+ file system).  This is primarily due to Unity’s asset
+    database, and how it stores paths to map them to GUID values.  Of course we
+    tried to be smart in the early days, but if you don’t set up a way to actually
+    verify that what you’re doing works on a case-sensitive file system, then it
+    will never fail that some well-intentioned programmer throws a toLower() in
+    somewhere and ruins the party.
