   4 # now baked into the JavaScript engine rather than using the NSPR
   5 # routines that they were based on, i.e. types like PRArenaPool are changed
   6 # to JSArenaPool.

   8 # This script was used in 9/98 to facilitate the incorporation of some NSPR
   9 # code into the JS engine so as to minimize dependency on NSPR.
