I said "libraries and apps" to be general.  A single app may link to 
several libraries, agreed?  Each library may need to do some formatted 
text output.  (Russell thought I meant libraries on top of Lua, rather 
of libraries along side of Lua.)  So if each library takes the position 
that the standard printf functions are bloated and rolls their own, the 
total result (your app) could end up larger than if everyone had just 
used the (*single copy*) of the standard printf.
