  3# This script modifies C code to use the hijacked NSPR routines that are
  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.
  7#
  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.

 15#  -r         Reverse direction of transformation, i.e. JS ==> NSPR2
 16#  -outdir    Directory in which to place output files
