+    Add support for rospack_norecurse to avoid recursing into all subdirectories when looking for a package.
+    
+    I am installing ros into /usr, hence this searches in /usr/share. I have a lot of directories, not ROS related, into /usr/share (e.g. a full TeX Live install), and I get these timings:
+    
+    Without rospack_norecurse in /usr/share:
+    $ time rosversion rospack
+    2.2.5
+    
+    real    0m2.861s
+    user    0m1.588s
+    sys     0m1.267s
+    
+    With rospack_norecurse in /usr/share:
+    $ time rosversion rospack
+    2.2.5
+    
+    real    0m0.135s
+    user    0m0.100s
+    sys     0m0.034s
+    
+    This is on a desktop with a SSD drive. On an arm board, with much less packages in /usr/share but way much slower I/O I remember hitting the 10 seconds timeout for roscore to start.
