Michal Mocny commented on CB-2207:
----------------------------------

cp does have a -l, just not on the default cp available on osx (you can replace 
it with gnu cp, but thats not a good option).  However, according to [1] rsync 
has a --link-dest option, and has been available since osx 10.5.

>From the man page:

[...] unchanged files are hard linked from DIR to the destination directory.  
The files must be identical in all preserved attributes [...]

> Pretty annoying when you make changes and click Play and your changes aren't 
> there. I think we can fix this by changing the project template's custom 
> build step from:
> touch -cm ${PROJECT_DIR}/www
> to:
> rm -rf "$BUILT_PRODUCTS_DIR/$FULL_PRODUCT_NAME/www"
> exec cp -R www "$BUILT_PRODUCTS_DIR/$FULL_PRODUCT_NAME/www"
> Any objections?
